“…Moreover, fertiliser trees can reduce weed problems and improve soil properties such as water uptake and P-supply. A few examples of agroforestry and other types of intercropping in Europe demonstrates potential for improved total yield and resource use, which however is not widely used in practice (Malézieux et al, 2009). …”

There is an increased understanding that the challenges of producing enough food and biomass while preserving soil, water and biodiversity necessary for ecosystem services can not be solved by prevalent types of conventional agriculture and that agro-ecological approaches and ecological intensification is fundamental for our future food production. FAO has stated that "Ecosystem services sustain agricultural productivity and resilience" and advocates production intensification through ecosystem management. Terminologies such as agro-ecology and ecological/ eco-functional/sustainable intensification are being proposed for agricultural development, which builds on higher input of knowledge, observation skills and management and improved use of agro-ecological methods. Contrary, increased global demand for food, and non-food biomass has increased the pressure for intensifying land use and increasing crop yields based on conventional inputs, while still aiming at reducing environmental impact. There is a battle of discourse between these approaches in competition foramong others -research and development funding. The examples of improved local food security from introducing agro-ecological and low external input agriculture practices among smallholder farmers are many. However, upscaling remains a challenge and the ability of such eco-functional intensification to feed the increased urban populations in emerging economies remains an open question. A broader view of what is organic and conventional farming is necessary and the use of new understandings from ecology and molecular biology will be needed to create and profit from synergies between preserving and building on eco-systems services and providing increased food and biomass.

“…An LER greater than 1.0 indicated inter-cropped systems were advantageous, whereas an LER less than 1.0 showed a yield disadvantage (Malézieux et al, 2009;Lithourgidis et al, 2011b). Drought greatly affected LER values in 2012.…”

“…Yields were separated into grain and total plant dry matter. Land equivalent ratio (LER) values were calculated using wheat and alternative crop data as: LER = mixed yield1/pure yield1 + mixed yield2/pure yield2 (Malézieux et al, 2009). The resulting value indicated the amount of land needed to grow both crops together compared with the amount of land needed to grow a mono-crop of each.…”

“…A land equivalent ratio (LER) shows the efficiency of intercropping for using the environmental resources compared with mono-cropping by comparing yields from growing two or more species together with yields from growing the same crops as a mono-crop (Malézieux et al, 2009;Lithourgidis et al, 2011b). An LER greater than 1.0 indicated inter-cropped systems were advantageous, whereas an LER less than 1.0 showed a yield disadvantage (Malézieux et al, 2009;Lithourgidis et al, 2011b).…”

Inter- and Double-crop Yield Response to Alternative Crop Planting Dates

Planting date is an integral part of a successful double-crop system, and in intercropping it can affect crop yields. Cool-adapted species that can be frost-seeded benefit from an earlier planting date by taking advantage of unused light and space between rows of slow-growing spring or fall crops such as winter wheat. This research evaluated differences between early frost-seeding, midseason relay-intercropping, and double-cropping planting dates of alternative crops (buckwheat, sunflower, radish, faba bean, and hairy vetch) on wheat and alternative crop yields. Field research took place in 2012 and 2013 near Novelty, Missouri. Wheat yields were affected by cropping system and alternative crop selection with significant differences up to 455 kg ha -1 . Alternative crop yields were harder to determine. In 2012, emergence occurred but drought precluded alternative crop yields for the frost-seeded and relay-intercrop systems. However, in 2013, planting date and cropping system affected alternative crops differently, with land equivalent ratio (LER) values showing an advantage for alternative crops when they survived past emergence. In both years, frostseeding provided yield advantages among almost all alternative crops. This research shows that farmers could increase their yield potential for a given field and perhaps produce additional forage or green manure yields in a year with a less severe drought by using alternative crops.

Focusing on the response of soil mesofauna to winter rye cultivation in monoculture for 90 years, the study investigated the abundance and diversity of soil-dwelling springtails, in relation to a five-field crop rotation. A long-term monoculture experiment was established in Poland in 1923 and has been continued uninterruptedly to the present time. Soil samples were taken over a period of three years (2011)(2012)(2013) to determine springtail (Collembola) abundance, species composition and life-forms spectra. We hypothesize that the crop rotation indirectly, due to the residues from the previous crops and modified soil conditions, caused the increase of the abundance and species diversity of springtails in comparison to monoculture. Generally, springtails were more abundant in the soil of rye field cultivated within a 5-field crop rotation. For the majority of sampling dates the abundance of springtails was higher in that habitat in comparison to the monoculture. Also, the calculated ecological indices showed greater diversity in the crop rotation. This treatment was dominated by the three species -Hypogastrura manubrialis, Mesaphorura macrochaeta and Ceratophysella denticulata, but in the monoculture only M. macrochaeta was distinctly numerous. Hemiedaphic springtails dominated in the crop rotation, whereas in the monoculture the most abundant were euedaphic representatives. The results of principal component analysis (PCA) indicated that the studied organisms were influenced by two factors -treatment and the sampling date. We suspect that the unbeneficial soil conditions in certain sampling dates had greater impact on Collembola community than the crop rotation system.
