weed seed bank dynamics during a five-year crop rotation 1 DD Buhler,KA Kohler,RL Thompson 被引量: 0发表: 2017年 Weed Seedbank Dynamics in Three Organic Farming Crop Rotations Weed management is a primary concern of organic farmers. Croprotation is an important potential management approach for...
The objective of the research was to determine the effect of long-term fertilisation (Ca, CaNPK, NPK) and crop rotation systems (rye monoculture without fertilisation with manure and five-field rotation with legume crop and manure fertilisation) on selected physical and chemical soi...
3、He grew a different crop on the same field five years in a row, what researchers call crop rotation.他连续5年在同一块地里种植不同的作物,研究人员称之为轮作。4、He checked me three times in a row.他连将我三次。5、For the second year in a row, France has fielded an expert team ...
Methods A five-year (ten consecutive crop seasons) pot experiment was conducted using four paddy soils with three P concentrations (2 P-rich, 1 P-moderate, and 1 P-deficient soils) from the TLR under four P fertilization regimes: P fertilization only for the wheat season (PW), P ...
S2a. In the soybean system (east field), cover crop biomass was 1.12 ± 0.33 Mg ha−1 compared to 0.57 ± 0.22 Mg ha−1 observed in the corn system (west field). However, in 2019, the year all soil and litter samples were collected, cover crop biomass in the soybean...
