Nitrogen (N) transformation in soil directly determines the effectiveness of N for plant growth. Biochar has received evermore attention because its significant ability to improve soil. However, effects biochar on N-related microorganisms (Lycopersicon esculentum Mill.) tomato cultivation soil, transformation, utilisation water and fertiliser, yield remain unclear. The objective this study was ...

For 2 years (2019–2020), a field experiment to test the activities of different fertilisation schemes on yield, colour and health status five grass mixtures for football pitches was conducted. Two were composed varieties perennial ryegrass, one mixture ryegrass Kentucky bluegrass, consisted species Lolium perenne, Festuca rubra, arundinacea Poa pratensis, seeds only variety sowed in plot. Three...

An assessment is made of the factors influencing high country pastoral production, their degree of science validation and an estimate of their effect on total run production. Fertiliser, and introduced pasture species suited to the rate of fertiliser input are the main avenues for increased biological productivity; and stock nutrition and breeding as the means of producing a specialised product.

Largest branch diameter in the breast-height region (LLBH) and acoustic velocity on lower bole were measured on trees in a 20-year-old Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) experiment comparing seven density management/fertiliser regimes. The less dense regimes tended to have larger mean branch diameter at breast height, with fertiliser increasing the mean even further. However, ex...

Nitrogen (N) is an essential nutrient for plant growth. In grazed pasture systems in New Zealand, N fertiliser regularly applied to maintain high productivity of ryegrass (Lolium perenne L.)/white clover (Trifolium repens L.) pastures. Several decades trials/research have established the scientific basis management and application grass/clover systems. However, despite, or perhaps because rich ...

Much of modern agriculture is based on immense populations of genetically identical or near-identical varieties, called cultivars. However, advancement of knowledge, and thus experimental utility, is found through biodiversity, whether naturally-found or induced by the experimenter. Globally we are confronted by ever-growing food and energy challenges. Here we demonstrate how such biodiversity ...
