Abstract Biochar amendment may improve crop growth through its nutrients and indirect fertility. However, this improvement varies in a wide range of biochars, crops, and soils. Our objectives were to determine the response of crop growth to biochar amendment and to assess the N use efficiency relative to the biochar and the soil types. In this pot experiment, we investigated five typical agricultural soils in China amended with two biochars. Four treatments were designed: the soil itself as a…

Abstract Various responses of plant growth attributes to the combined application of biochar and mineral fertilizers were reported according to trial conditions. Thus we studied the effects of

Biochar as a carrier for nitrogen plant nutrition : 2 , The growth of maize ( Zea mays L . ) applied with nitrogen enriched biochar on different soil texture

A green house experiment was carried out to study the effect of nitrogen enriched biochar on the growth of maize and the efficiency of nitrogen fertilization. Maize was planted in soils with

Investigations of the effect of the amount of biochar on soil porosity and aggregation and crop yields on fertilized black soil in northern China

TLDR
The use of controlled amounts of maize-straw biochar in black soil is beneficial for improving crop yields and levels of soil aggregation, however, the use of excessive amounts of biochar results in unfavorable aggregate formation which negatively impacts the yields of crop growth.

TLDR
Rice straw biochar addition at 9 t ha–1 with 90-120 kg N ha-1 with biochar can be recommended for sustainable rice productivity and improvement of rice yield and farmers’ profits.

Biochar and Its Broad Impacts in Soil Quality and Fertility, Nutrient Leaching and Crop Productivity: A Review

Biochar is gaining significant attention due to its potential for carbon (C) sequestration, improvement of soil health, fertility enhancement, and crop productivity and quality. In this review, we
