Seasonal conditions During the period of the field trials, annual rainfall was generally.

growers should soil test in late winter or early spring to a depth of 30 cm to determine the application rate for the following spring.

The average soil mineral N from 10 years of trials is 38 kg N/ha. On average a target total N (soil and applied) of kg N/ha will increase seed yield. Rather, weight gain on older pastures was restricted by pasture quality in winter and by reduced pasture growth in spring, but not by presentation dry-matter yield.

The decrease in pasture productivity seemed to be primarily due to reductions in available soil mineral N with age, since the N concentration of plant shoots decreased as a pasture by: A 3‐year grazed grass with clover (grass + clover) ley in a 5‐year rotation with arable crops increased percentage organic carbon (%OC) in the top 25 cm of the soil from to in World grain production increased by % between and comprising +% for yield and a much smaller increase (31%) in crop area, with more than half of the latter coming from increased intensity of cropping on existing arable a result per capita food availability has improved notably for a population that has risen %, and real food prices have fallen overall ().Cited by:   The sequestration in soil of organic carbon (SOC) derived from atmospheric carbon dioxide (CO 2) by replacing arable crops with leys, has been measured over 70 years on a sandy loam experiment was designed initially to test the effect of leys on the yields of arable crops.

A 3‐year grazed grass with clover (grass + clover) ley in a 5‐year rotation with arable crops increased Cited by: 9. The rationale behind arable cropping is that more nutrients, in particularly soil P, are removed from the soil by the crop than are added as inputs (Marrs et al., ).

However, increased off-take of nutrients within the crop has not always been followed by significant reductions in soil concentrations (e.g., Marrs et al., ; McCrea et al Cited by:   I tested whether the non-fertilizer N supply of grassland soils (NFNS; N uptake on unfertilized plots) affects the relationships between N uptake and dry matter production, N application and N uptake, N application and dry matter production, as well as the optimum fertilizer application rate.

At low N uptake rates the amount of dry matter production per kg of N uptake was negatively correlated Cited by: 8. Soil under Grass — Are these changes in near-surface soil organic C common. Data from Causarano et al.

Introduction. In arable cropping systems, grass crops may serve other purposes besides that of seed production. Undersown in main crops (e.g. cereals) grass may provide an effective nitrate catch crop during the autumn and winter period (e.g.

Thomsen and Christensen, ).Leys included in arable rotations are used for grazing, cutting and silage by: This paper reviews animal treading and the associated effects on soil physical properties and pasture productivity from treading-induced soil compaction and pugging.

Response curve relationships between soil physical properties (e.g. macroporosity, air-filled porosity, bulk density) and pasture and crop yield are reviewed.

Optimum soil macroporosity for maximum pasture and crop yield ranges Cited by: The grass-arable system is characterized by a build-up of soil-N during the grass-phase, especially under grazing, and a decrease of soil-N during the arable phase.
