A three-year field trial on an upland loessial soil (Belmont silt loam) in New Zealand investigated the effects of ripping, application of fertilizer N and grazing management on the recovery of some physical, chemical and biochemical properties of so

Total, extractable, and microbial C, N, and P, soil respiration, and the water stability of soil aggregates in the F-H layer and top 20 cm of soil of a New Zealand yellow-brown earth (Typic Dystrochrept) were compared under long-term indigenous nativ

SUMMARYThree field experiments in Eastern England, in which 15N-labelled fertilizer had been applied to winter wheat, were used to measure the persistence of the labelled N remaining in soil and stubble at harvest and the availability of this N to up

SUMMARYA computer model is presented that describes the flow of nitrogen between crop and soil on the field scale. The model has a compartmental structure and runs on a weekly time-step. Nitrogen enters via atmospheric deposition and by application o

The effect of a pastoral fallow (the 'spelling' of a pasture from early spring (September) to autumn (April/May)), with or without added fertiliser, on pasture and legume growth rates, total pasture biomass accumulation, nitrogen fixation, and on soi

Factors influencing rates of C and N mineralization of soil and plant materials, and the reliability of different procedures for estimating microbial biomass, were measured in a soil (Typic Dystrochrept) that had been restored under grazed pasture in

Fertiliser experiments were conducted on soils fom the uplands of 'Eua, Tonga, which are being developed for forest farming (pastures under trees). Glasshouse pot trials were used to demonstrate nutrient deficiencies and the likely level of fertilise

SUMMARYThe recovery of autumn-applied labelled fertilizer N in winter wheat and in the soil and roots was measured in five experiments on three soil types in eastern England. In four of the experiments, crop recoveries of fertilizer N ranged from 11

The mineralisation of nitrogen (N) under aerobic and anaerobic (waterlogged) conditions, and the microbial biomass carbon (C) content (using the substrate-induced respiration method) were measured in a range of plant litters, peats, and soils of mode
