Salt tolerance of agricultural crops has been expressed as the yield decrease due to a certain salt concentration within the root zone as compared to a non-saline control. The most well-known plant response curve to salinity has been a piece-wise linear regression relating crop yield to root zone salinity. This method used the hypothesis that crops tolerate salt up to a threshold after which their yield decreases approximately linearly. Critique to this method included its lack of sensitivity to dynamic factors such as weather conditions. As a result, other classification indices have been developed, but none is as well accepted as the threshold-slope model. In addition to a mini-review of the key salt tolerance studies, our objective was to classify salt tolerance levels of poplars and willows. Initial classification showed that salt tolerance of these genera ranged from sensitive to moderately tolerant.

However, alley cropping for woody biomass production is of interest because of its high potential to concurrently provide a biomass feedstock and an arable crop. One of the systems that exists, although at an experimental level, is the integration of rows of fast growing trees, such as poplar or willow, with arable crops. The experimental plots were initially established as part of the German joint research project “AgroForstEnergie - Economic and Ecological Evaluation of Agroforestry Systems in Farming Practice“, funded by the German Federal Ministry of Food and Agriculture (AgroForstEnergie 2015). The goal of this project was to study alley cropping systems, which concurrently produce a woody biomass feedstock and conventional agricultural crops. Currently the work is continued through the AGFORWARD Project. The State of Brandenburg is known for its light sandy soils that are prone to wind erosion. The introduction of tree hedgerows within the agricultural landscape can reduce wind erosion (Böhm et al. 2014). In addition, microclimatic conditions such as soil moisture, wind speed reduction, relative humidity and air temperature have been more favourable for plant growth in crop alleys compared to reference crop areas (Böhm et al. 2014; Quinkenstein et al. 2009). Sugar beets are a common crop for conventional agricultural systems in Western Europe. As part of agroforestry systems, sugar beets have rarely been studied. Even though sugar beets can root up to a depth of 2 meter, their yields can be significantly reduced due to a lack of water (Hoffmann 2010; Bloch et al. 2006). Agroforestry systems that consist of tree hedgerows and crop alleys, also known as Alley Cropping Systems, have the potential to increase plant moisture in comparison to conventional agricultural systems (Quinkenstein et al. 2009). This study aims to assess tree hedgerow effects on sugar beets. The objectives of this study were to; 1) assess how tree hedgerows planted at three distances affected sugar beet yields; 2) to correlate soil moisture values of the top 15 cm with sugar beet yields at the same distance of the tree row; 3) to assess the effects of drought stress on sugar beet yield.

Examples of traditional agroforestry (AF) in central Europe are orchard meadows "Streuosbt", hedgerows "Knicks" and windbreaks. Traditional AF systems are considered to be areas of high natural and cultural value (HNCV), and as such have been recognized to support high biodiversity levels. Recently, modern AF systems which are well adapted to the current farming practices and are compatible with mechanized agriculture have emerged. Modern practices such as alley cropping system for woody biomass production (ACS), composed of strips of fast growing trees and agricultural crops grown in alleys between the tree rows, can supply market goods and environmental services at the same time (Gruenewald et al. 2007, Quinkenstein et al. 2009). However, farmers in Germany have been reluctant to implement the latter systems, because agricultural policies have limited the number of trees within agricultural systems, while the former have been in danger of abandonment throughout Europe. As a result many farmers have lost interest in AF, and those that inherited land with traditional AF systems may not recognize them as such, because they are not recognized as AF according to the EU policy. The aim of this work was to investigate familiarity with agroforestry in Germany.

Agroforestry systems have the potential to improve on-farm use of water through enhanced soil water holding capacities, the provision of shade, and the creation of wind shelter. These three characteristics can also improve the resilience of agricultural production in response to changing weather patterns. The objectives of this study were: 1) to measure how alley cropping systems with varying alley widths affect crop microclimate, 2) to measure the effects of this microclimate on sugar beet (Beta vulgaris) yields, and 3) to assess how moisture availability affects sugar beet growth patterns. Measurements were made in a 70 ha alley cropping system comprising black locust (Robinia pseudoacacia L.) and hybrid poplar Max1 (Populus suaveolens subsp. maximowiczii x P. nigra). A sugar beet crop was grown during the relatively dry growing season of 2015. Sugar beet yields were reduced in close proximity to the hedgerow, but yields were higher at and beyond an intermediate distance when compared with those in a nearby conventional agricultural field. Moisture availability significantly affected growth patterns of sugar beet roots.

For example, trees in agroforestry systems can provide shelter for wildlife and supply additional nutrients to adjacent arable fields through leaf litter inputs and fine root turnover. In addition, tree-strips have the ability to improve the groundwater quality underneath the tree-strip itself and possibly underneath adjacent fields. Unlike these commonly measured ecosystem services the microclimate conditions in temperate agroforestry systems are still a comparatively new study area (Kanzler et al. 2015, Böhm et al. 2014). This might be due to the complexity of the microclimate, which depends on various parameters such as the plant height, the planting density, and the orientation of the tree-strips. The objective of this study was to investigate the potential influence of tree-strips on microclimate using high resolution data loggers.

September 2016, Gießen N2 - Der parallele Anbau von Ackerfrüchten und Agrarholz in Agroforstsystemen führt zu einer ökologischen Aufwertung der landwirtschaftlichen Nutzfläche und hat auch positive Auswirkungen auf das Mikroklima zwischen den Gehölzstreifen. Bei streifenförmigen Agroforstsystemen (Alley Cropping) in Brandenburg konnte eine deutliche Reduktion der Windgeschwindigkeit und von Temperaturextremen sowie ein Anstieg der relativen Luftfeuchtigkeit beobachtet werden (Böhm et al. 2014, Kanzler et al. 2015). Eine Reduzierung der Windgeschwindigkeit führt zudem zu einer Minderung der potentiellen Evaporation. Dabei stellt sich die Frage, wie sich diese Veränderungen kleinräumig auf die gemessene Evaporation und auf die Produktivität der Ackerkulturen auswirken.
