Abstract:
... In a multi-year experiment, weed infestation of pea crop in three tillage systems was analyzed: a) conventional tillage (CT), b) reduced tillage (RT), and c) no-tillage (NT), and in two terms: 1) at 2–3 pea leaves stage (23–25 stage in BBCH scale) and 2) at the flat pod stage (75–79 BBCH). Treatments conducted in the CT system included shallow ploughing and pre-winter ploughing in the autumn. In t ...

Abstract:
... The rate of change in the relative size of SOC pools (sensitivity) due to land management may vary depending on their level of chemical and/or physical protection from decomposition, but has rarely been directly measured. The availability of archived (1975) soils from an abandoned long term tillage treatment experiment provided a unique opportunity to assess the sensitivity of SOC pools with diffe ...

Three areas under no-tillage (7, 11 and 14 years of cultivation) were evaluated and compared to adjacent areas of the Cerrado not impacted by agriculture. Results indicated that although no-tillage is a conservation system, it has either slightly ...

Abstract:
... Crop rotation systems in organic and conventional farming systems differ in crop types, management and duration. However, changes in arthropod communities over the entire rotation system are poorly understood, as many studies have surveyed only single years or have not covered the entire rotation period. Here, we describe changes in arthropods in two contrasting systems at a split organic‐conventi ...

We tested the hypothesis that soil suppres ...

Abstract:
... The rice-wheat rotation is the dominant cropping pattern in the Terai ‘food basket’ of Nepal. Current production practices require significant labor, water, and energy which erode profitability and, hence, incentives for intensification. Dry direct seeded rice (DSR) and zero tillage wheat (ZTW) have been widely tested on experiment stations as alternative establishment technologies in South Asia. ...
