To predict the amount of crop residue remaining on a field at a given time, the rates of residue decomposition under conditions of low temperature or low water potentials need to be known. Laboratory experiments were made in which temperature and moi

Evidence indicates a strong positive relationship between increases in nitrogen fertilizer use on cropland and nitrate concentrations in shallow ground water. This raises concern about the fate and efficiency of nitrogen fertilizer with current farmi

Modern large-scale conventional agriculture with intensive monoculture and row-cropping practices often results in unacceptable soil erosion and runoff and in associated losses of nutrients and pesticides. It also adversely affects wildlife. Sediment

A nonfluorescent rifampicin-resistant Pseudomonas spp capable of producing a toxin inhibitory to the growth of wheat roots was inoculated onto nonsterile wheat straw at 10 4 or 10 6 colony-forming units (cfu) g −1 dry wt and incubated at several wa

Conventional, intensive tillage farming systems have greatly increased crop production and labour efficiency. But, serious questions are being raised about the energy-intensive nature of these systems and their adverse effects on soil productivity an
