Characteristics of crop residues
Agricultural Wastes, 1986Abstract This paper reports the results of work carried out to determine the characteristics of the residues of important agricultural crops in North India. Density, equilibrium moisture content, higher calorific value and the results of chemical, proximate, elemental and thermogravimetric analyses of the crop residues are reported and discussed.

In less affluent countries such as those in South and Southeast Asia, grain is directly used for human consumption, and crop residues are the main source of fodder for animals. In addition, crop residues have several other uses (Table 1). Crop residues are certainly an asset in these countries and seldom are left in the field.

Pyrethroid insecticide residues on vegetable crops
Pest Management Science, 2001Abstract Pyrethroid insecticides were applied on various vegetable crops as foliar treatments to determine dissipation rates. On Chinese broccoli (Guy Lon), Chinese mustard (Pak Choi) and Chinese cabbage (Kasumi, napa), fenvalerate was persistent with residues of 0.10, 0.14 and 0.11 mg kg −1

Visualizing soil surfaces and crop residues
IEEE Computer Graphics and Applications, 1993A test case for visualizing field and laboratory data pertaining to soil erosion and infiltration is examined. Several visualization techniques were used to derive image data from an experiment in which the effect of a sequence of five rainfalls on a laboratory-formed soil surface was measured.

Identification of pentachlorobenzonitrile residues in field crops
Bulletin of Environmental Contamination and Toxicology, 1977We recently received several carrot extracts from another FDA district laboratory for identification of a material present in each of the extracts which had a GLC retention time inconsistent with that of any known pesticide. The material, which was eluted from Florisil with 15% ether in petroleum ether (AOAC, par.

Parathion residues on leafy crops
1963In Germany, during World War II, G. SchraDer developed the compound E-605 (O,O-diethyl-O-p-nitrophenyl thiophosphate) which is commonly known as parathion. It was soon discovered that this organophosphate was an extremely effective insecticide against a number of insect species.

The determination of residues of dichlorvos in crops and tissues
The Analyst, 1970An analytical method for determining residues of dichlorvos with a limit of determination of 0·01 p.p.m. is described. It is intended for use by those laboratories which carry out residue analysis for regulatory purposes, with an emphasis on speed, specificity and sensitivity.Residues of dichlorvos are extracted with either dichloromethane or ethyl ...

Effects of prior crop residue management on microbial properties and crop residue decomposition
Applied Soil Ecology, 1998A litterbag decomposition experiment was conducted to test the hypothesis that differences in crop residue management practices influence the size and activity of the microbial community that regulates residue decomposition. Residues of wheat (Triticum aestivum), barley (Hordeum uulgare) and lupin (Lupinus albus) were incorporated into soils in which ...

INSECTICIDE RESIDUES IN COTTON CROP SOIL
Journal of Environmental Science and Health, Part B, 2001Dimethoate, monocrotophos, triazophos, deltamethrin, cypermethrin and endosulfan were applied to a cotton crop soil located at Nurpur village, Punjab, India. The insecticides were applied sequentially at recommended dosages in cotton fields by foliar application in 1995, 1996 and 1998.

Managing Crop Residues for the Retention of Carbon
Water, Air, & Soil Pollution, 1993Soil organic matter, a major sink for carbon, is controlled by many factors that have complex interactions. The management of crop residues is of primary importance. Reduced tillage and no-tillage practices result in a significant build-up of soil organic matter because they greatly reduce the rates of decomposition of both the native soil organic ...
