TL;DR: In this paper, the authors tested two hypotheses: i) land use and management practices affect microbial properties (microbial biomass and enzyme activities) in topsoil (0-20 cm), but have no effects in subsoils (20-100 cm).

TL;DR: In this article, the authors investigated how conventional and organic farming influence the erosion rate of soil, due to row crops cultivated on mountainous farmland in the presence or absence of agricultural chemicals, and concluded that organic farming alone cannot be used to effectively control erosion, and that both farming systems require additional conservation measures such as winter cover crops and residue mulching, to sufficiently prevent soil loss for row crop cultivation.

TL;DR: In this article, the quality of percolating water in the vadose zone, underlying both organic and conventional intensive greenhouses, was measured in newly established farms where the subsurface underlying the greenhouses has been monitored continuously from their establishment.
Abstract: It is commonly presumed that organic agriculture causes only minimal environmental pollution. In this study, we measured the quality of percolating water in the vadose zone, underlying both organic and conventional intensive greenhouses. Our study was conducted in newly established farms where the subsurface underlying the greenhouses has been monitored continuously from their establishment. Surprisingly, intensive organic agriculture relying on solid organic matter, such as composted manure that is implemented in the soil prior to planting as the sole fertilizer, resulted in significant down-leaching of nitrate through the vadose zone to the groundwater. On the other hand, similar intensive agriculture that implemented liquid fertilizer through drip irrigation, as commonly practiced in conventional agriculture, resulted in much lower rates of pollution of the vadose zone and groundwater. It has been shown that accurate fertilization methods that distribute the fertilizers through the irrigation system, according to plant demand, during the growing season dramatically reduce the potential for groundwater contamination from both organic and conventional greenhouses.

TL;DR: In this article, the authors describe a model designed for analyzing interrelated nitrogen fluxes in farming systems, which combines the partial N balance, farm gate balance, barn balance and soil surface balance, in order to analyse all relevant N fluxes between the subsystems soil-plant-animal-environment and to reflect conclusive and consistent management systems.

TL;DR: The feasibility of new breeding techniques for rewilding, a process involving the reintroduction of properties from the wild relatives of crops, as a method to close the productivity gap, is discussed.
