Controlled traffic farming (CTF) is a mechanisation system in which all machinery has the same (or modular) working and track width so that field can be confined to least possible area of permanent lanes. CTF enables productivity non-compacted crop beds optimised for given energy, fertiliser water (rainfall) inputs. This study investigated agronomic response economic return grain sorghum grown ...

Slow-release nitrogen fertiliser can potentially increase crop production and improve use efficiency. However, it is unclear that are suitable for different regions crops in the northeast of China. Therefore, according to soil climate characteristics, we investigated synchronised relationships between slow release maize requirements. Experiments were conducted at Shenyang Agricultural Universit...

Fertilisation with animal manure has a long-standing tradition as way to close nutrient cycles on farms. However, the fate of nitrogen (N) from in soil beyond year application remains poorly understood. The aim this research was understand residual N fertiliser value mineral (Min) and cattle slurry (Slu) relation partitioning fertilisers different physical fractions. To end, we characterised 15...

The effects of routine and luxury weed control and fertilization treatments on diameter, height, carbon (δC) and nitrogen (δN) isotope composition in foliage were assessed in an 8-year-old, F1 hybrid pine (Pinus elliottii var. elliottii Pinus caribaea var. hondurensis) plantation, on typical sandy soils in southeast Queensland. The aim of this research was to identify how weed control and ferti...

The circular economy concept promotes the recycling of agricultural waste. This study was aimed at investigating effects cattle horn shavings on apple tree nitrogen nutrition. Ligol trees P 60 rootstock were object study. experiment conducted in experimental orchard Institute Horticulture, Lithuanian Research Centre for Agriculture and Forestry, from 2015 to 2018. Two fertiliser rates tested: 5...

A two-year dairy study was conducted under irrigation at Lincoln, Canterbury, comparing 1. Moderate stocking rate (MSR, 3.9 cows/ha; comparative (CSR) of 89 kg live weight (LWT)/t DM (dry matter) offered; 150 nitrogen (N) fertiliser/ha/year; grain supplementation 0.55 t DM/cow/year; wintering cows off- farm); or 2. Low (LSR, 2.9 CSR 91 LWT/t grazing diverse pasture (Italian ryegrass, plantain, ...

Abstract A variety of organic feedstocks can be used for anaerobic digestion, resulting in digestates with different compositions, affecting the fertiliser value. Therefore, two experiments were conducted to assess (1) differences nitrogen (N) value seven from a 2-year field experiment spring wheat, and (2) degradability matter (OM) within an aerobic incubation experiment. In field, mineral equ...

The current work aimed to resolve some long-standing questions about the potential benefits and limitations of co-digestion of slaughterhouse wastes. To achieve this, a laboratory-scale trial was carried out using the mechanically recovered organic fraction of municipal solid waste mixed with either sheep blood or a mixture of pig intestines with flotation fat. Both of these co-substrates are d...
