Foreword
We all have a vision of what the future will look like and when it comes to technology we all have some visions of robots performing the jobs that most of us would happily pass up. The Industrial, Green and Digital Technological Revolutions have driven agricultural output to levels capable of feeding the exponential growth in human population to date. With a predicted world population increase from the 6.8 billion today to over 10 billion by 2050, growth in agricultural output will need to continue. This combined with an ever declining rural labour force and the need for greater efficiencies will inevitably lead to increasing levels of in-field automation. We‟ve all seen video clips of modern factories, with their robots doing the intricate and repetitive tasks faster and more consistently than possible with manual labour. Is this what the farm of the future will look like?

Abstract. Over the last two decades terrestrial and global 3D measurement sensors in the field of engineering geodesy have seen a significant upturn. With modern measurement techniques, a 3D trajectory of a moving object can be determined within a few centimetres (mostly with Global Navigation Satellite Systems, GNSS), under certain circumstances and with an overall understanding of the applied method accuracies of within five to ten millimetres can be achieved (tracking total station). New application areas have now been created in the fields of construction, mining and agriculture.

Vorwort
Welternährung und Klimaschutz sind eng miteinander verknüpft. Etwa 13,5 % der globalen Treibhausgasemissionen werden unmittelbar durch landwirtschaftliche Produktion verursacht. Weitere 12 % entstehen durch Ausweitung landwirtschaftlicher Flächen auf Kosten von Wäldern, natürlichem Grasland, Mooren etc. Das im Holz und Bodenhumus gespeicherte CO2 wird dabei freigesetzt. Mit der rasant steigenden Nachfrage nach Lebensmitteln und nachwachsenden Rohstoffen wächst auf die Landwirtschaft der Druck, mehr zu produzieren. Nach Schätzungen der FAO wird beispielsweise der Bedarf an Getreide zwischen 2000 und 2030 um mehr als 40 % ansteigen.

Introduction: biodiversity, agriculture and the Common Agricultural Policy (CAP)
Europe’s agricultural sector has received sustained public support under the Common Agricultural Policy (CAP) over the last 50 years. This support has evolved alongside growing recognition and awareness of the strong links between agricultural production and biological diversity conservation. On one hand, it was recognised that changing agricultural land use is a major cause of the decline of biodiversity in Europe. Whereas on better land farming systems have generally intensified, poorer land has been subject to abandonment or afforestation. Traditional, low-intensity farming systems with high nature value have gradually and steadily disappeared (EEA, 2009a).

Introduction

Managing frost risk in New Zealand vineyards has been at the forefront of growers’ minds after severe frost damage to the 2001 and 2003 vintage. Hawke’s Bay Grape Growers Association estimated their growers lost 40 percent of their 2001 crop from frost damage (Wairarapa Times-Age, 2001). There has been a subsequent increase in interest and investment in frost protection methods as growers seek to protect their crop. Frost protection is an expensive exercise, whether it be use of helicopters during the night, wind machines to mix inversion layers or sprinkler systems.

Abstract

Variation in field application from a centrifugal fertiliser spreader has, in the past, been difficult to assess due to the intensive field testing required. However, with the application of current technologies such as Global Positioning Systems and Geographic Information Systems, the assessment of field application variation is now possible. The aim of this research was to develop a method to assess field application variation using basic transverse spread pattern test and vehicle tracking data. The information was used to measure and compare the effect of spread pattern, driving accuracy, driving method and paddock shape. Two differently shaped paddocks were used for analysis, one rectangular, the other triangular.

ABSTRACT.

Fertilizer spreader testing plays an important part in achieving accurate, uniform application of nutrients to the land; however, current testing methods are often laborious, with high levels of manual input required to obtain specific spread characteristic information. This study aimed to review and identify potential techniques and test one that could be incorporated into a spreader testing program. A review of available spreader tests throughout the world showed varying results. Measurement systems requiring a mathematical algorithm to calculate the landing position of individual particles were found to be quick interpolators, but inaccurate. Tray collection, used extensively by quality assurance programs throughout the world, is accurate in producing distribution pattern results; however, it is a laborious task, especially when analyzing multiple spread patterns for variable-rate application. An image-processing method showed the greatest potential as a rapid analysis and interpretation tool of spread pattern data.

Abstract
Collecting accurate fertiliser distribution information from large field trials is difficult and very labor intensive. A computer analysis method was developed for analysing field application variation of fertiliser distribution from any spreading vehicle. The tool used measured machine parameters including geographical position and a series of static spread patterns from the spreading vehicle to create application surfaces. The tool proved to be effective for calculating an accurate representation of field application variation and should have many uses in fertiliser application research.

Introduction
Following the introduction of Precision Viticulture (PV) technologies to the Australian wine industry in the late 1990’s, and the associated research during the intervening years, an increasing number of grape and wine producers are recognising the value of understanding the inherent biophysical characteristics and performance of their vineyards for improved viticultural management and decision-making. By definition, PV is viewed as a continuous cyclical process of observation, evaluation and interpretation leading to the implementation of a targeted management plan, followed by further observation and refinement of the management plan if required (Proffitt et al., 2006). The rationale behind this process is that through the use of spatial information, any given viticulture decision has an increased likelihood of delivering the desired or expected outcome compared to a similar decision made in the absence of such information.

Increasingly severe water constraints
Though subject to ocean flow, southwestern Europe is very much affected by climate change which increases the variability of precipitation and the need for water in the face of increasingly frequent hot southern gusts. We observe a northward shift in water constraints that increases the average deficit during the main farming period from April to September (see Map 2) while rainwater resources from October to March are still insufficient for the entire Mediterranean perimeter (see Map 1).

Introduction
India has witnessed an increase in food grain production from 51 million tonnes (50’s) to 206 million tonnes at the turn of the century and that has helped in achieving self sufficiency. However, quick shrinking of the agricultural land threatens sustainable production of food grains and its ability to feed ever growing mouths. In this context, careful tailoring of soil and crop management practices suitable to local needs is of great importance to keep up the pace of production. Precision Farming otherwise called prescription farming or site-specific farming helps to overcome these constraints by accurately assessing the variability of crop production practices in space-time continuum by utilizing tools like Global Positioning System (GPS), Geographical Information System (GIS), Remote Sensing (RS) and Sensors.

FOREWORD

This report provides a snapshot of the overwhelming evidence that we need better environmental practices if we want to ensure ongoing productive agricultural systems and food security in South Africa. It also serves to underpin WWF’s drive to promote the protection of natural ecosystems, which produce the critical goods and services that underpin agricultural practices in the country. We have not attempted to specify every issue, but rather aimed to provide a broad view of the negative impacts of agricultural development that is focused on maximum productivity by exploiting natural resources while disregarding the complex hidden costs – financial and otherwise – of food production. It also highlights some of the best-practice solutions we need to follow if we want to meet our growing demand for food and fibre – one of the key challenges of the 21st century.

ABSTRACT

From 2003 to their peak in mid 2008, the nominal prices of maize and wheat roughly doubled, while those of rice tripled in a matter of months rather than years. Although fundamental factors were clearly responsible for shifting the world to a higher equilibrium price during this time, there is little doubt that when food prices peaked in June 2008, they soared well above the new equilibrium price. Numerous arguments have been proposed to explain overshooting, including financial speculation, depreciation of the United States (U.S.) dollar, low interest rates, and reductions in grain stocks. However, observations that international rice prices surged in response to export restrictions by India and Vietnam suggested that trade-related factors could be an important basis for overshooting, especially given the very tangible link between export volumes and export prices.

Introduction
The market for organic produce continues to expand (Thompson, 2000). Kentucky has more than 75 acres of greenhouses with modified pond or tank hydroponic beds for “float” tobacco transplant production. The development of a certified organic greenhouse production system for lettuces and greens could allow Kentucky tobacco farmers access to a new market for their facilities as the tobacco market changes. In this study, commercial organic fertilizers were used to grow ‘Ostinata’ Bibb and ‘Red Sails’ leaf lettuce in a pond, tank, or “float” production system.

ABSTRACT

In Northeast Thailand, dependence on agricultural productivity and geographical conditions contribute to underdevelopment and poverty. These factors can be alleviated by alternative farming techniques such as hydroponics. The goal of our project was to design and construct a hydroponic system for the MSU Demonstration School that can be integrated into the agricultural curriculum while introducing business skills. This report includes recommendations for our sponsor, the MSU SIFE team, to assess the operation and educational use of the hydroponic system.

Abstract:

A hydroponic system was developed and used for purification of an anaerobically treated dairy manure and production of forage crops. The effect of light duration, seeding rate and wastewater application rate on the crop yield and pollution potential reduction were studied. The results indicated that a wheat forage crop can be produced in 21 days from germination to harvest in this system and removal efficiencies of up to 89.9, 94.6, and 86.7 % can be achieved for the total solids, chemical oxygen demand (COD) and ammonium nitrogen, respectively. Increasing the wastewater application rate increased the crop yield and decreased the pollutants removal efficiencies. A treatment combination of wastewater application rate of 900 mL/day, a seeding rate of 400 g and a light duration of 12 hours gave the best results for crop yield (3.65 kg of wheat/tray). A total possible yield of 3160 tonnes per hectare per year can be achieved with the system (with thirteen harvests per year).

INTRODUCTION
The pH of the nutrient solution is a major determinant of nutrient uptake by the plants. The most suitable pH range for plants is recognized as 5.8 - 6.5 (Harris, 1988) (different crops will favor a different optimum pH). At low pH, cation absorption decreases and anion absorption increases and vice versa. The pH of the nutrient solution affects the solubility of nutrients, thus controlling the availability of nutrients to the plant (Smith, 2000). The type of nutrient and the amount of nutrients dissolved and the pH of the water source in which the nutrients are dissolved affect the pH of the nutrient solution (Bradley and Marulanda, 2000). If the pH of the nutrient solution is not in the favorable range, it has to be adjusted using a mild acid or a base as required before application. However, this is less feasible under low-input farming and home gardening scenarios.

Many people think of hydroponics as growing plants in water, but hydroponic production actually is defined as growing plants without soil. This production system may use a wide variety of organic and inorganic materials. The nutrient solution, rather than the media in which the plants are growing, always supplies most of the plant nutrient requirements. This method of growing has also been referred to as nutrient-solution culture, soilless culture, water culture, gravel culture and nutriculture.

Abstract: Water is increasingly becoming the most limiting resource needed to meet the growing population. Its crucial role in human life is highlighted in arid lands, where is recognized by low annual rainfall as well asuneven temporal and spatial distribution, resulting to dry and wet periods. Such climatic condition influenceswater availability and crop-yield stability. Therefore farming is problematic due to unpromising water access.The most important component of agriculture in arid lands is agriculture water use efficiency. Under low andvariable rainfall conditions, efficient irrigation management is a good way for improving water-use efficiency.Efficient and precision irrigation is a critical factor for sustainable agriculture. Water scarcity, as a major limitingfactor in arid and semi arid areas, forces for effective use of limited water, high productivity and field precisemanagement.

Abstract: Problem statement: The main purpose in this study is to provide a more rational platform in extension modeling to respond to the very recent world-wide warnings calling up for global revision of the present extension practices to put the appropriate science and technology to application to securing Clean-Green Sustainable Development (CGSD). Approach: To achieve this purpose, extension education was reconsidered through a new view lens of community empowerment. Results: The basic concern though, is based on CSD, self-sufficiency, food security and safety and entrepreneurship development in the agricultural sector and affiliated sub sectors. Fostering the development of catalytic leaders, researchers and educators who approach issues and challenges in research, education and extension from multiple perspectives and seeking to construct an integrated knowledge base upon which the practice of teaching, learning and human development is based are two other major concerns in this paper.
