The ability of layered double hydroxides for nitrate absorption and desorption in crop and fallow rotation
BACKGROUND AND OBJECTIVES: This study aims down to evaluate the ability of chloride magnesium- aluminium- layered double hydroxides (4:1) for nitrate adsorption from the soil solution in successive cropping periods. METHODS: The study was conductedunder long-term cropping periods, including first crop): bell pepper; second crop: mentheae; third crop: cher...
متن کاملStructure of weed communities occurring in crop rotation and monoculture of cereals
A strict field experiment with crops sown in crop rotation and monoculture wascarried out in the years 1988-2012 at the Experimental Station Uhrusk belonging tothe University of Life Sciences in Lublin, south-eastern Poland. The study wasaimed at evaluating the structure of weed communities occurring in crop rotationand monoculture of cereals. The highest weed density m-2 was determined inthe s...

15 صفحه اولCrop rotation modelling
For use in an Internet application on whole farm modelling we needed to determine a reasonable crop rotation given only the crops in the rotation and the number of hectares of each crop. The crop rotation problem considered in this paper is therefore that of determining hectares of precrops for each crop. Crop rotation modelling in general is traditionally done by using linear programming. In t...
متن کاملSpatial Relationships of Soil Texture and Crop Rotation to Aspergillus flavus Community Structure in South Texas.
ABSTRACT Aspergillus flavus, the causal agent of aflatoxin contamination of cottonseed, is a natural inhabitant of soils. A. flavus can be divided into the S and L strains, of which the S-strain isolates, on average, produce greater quantities of aflatoxins than the L-strain isolates. Aflatoxin contamination can be severe in several crops in South Texas. The structure of A. flavus communities r...
