Soil and Tillage Research, 2020
Abstract Straw incorporation into the soil can effectively solve the problem of extra harvested crop residues on the surface. However, due to the lack of research on the spatial distribution effects of straw in the soil after incorporation, it is difficult to evaluate the actual straw incorporation effects of tillage tools.

The effects of continuous straw returning strategies on SOC balance upon fresh straw incorporation
Environmental Research, 2023Continuous straw returning is widely encouraged for augmenting soil organic carbon (SOC) in arable lands. However, the magnitude of changes in net SOC related to native SOC mineralization and new SOC development upon fresh straw incorporation remains elusive, particularly in soils after continuous straw returning with different strategies.

Straw sizes were found to affect the methylmercury (MeHg) accumulation in rice grains induced by straw incorporation. The mechanism behind, however, still remains unclear. Here, we incorporated rice straw in different sizes (powder, 2 cm and 5 cm) into a Hg-contaminated paddy soil.

AbstractIn a laboratory experiment, incorporation of paddy straw in soil immobilized native as well as added fertilizer N and about half of the immobilized N was mineralized after 90 days of straw incorporation. Straw and N application alone or in combination increased biomass carbon, phosphatase and respiratory activities of the soil.

Straw incorporation and immobilization of spring‐applied nitrogen
Soil Use and Management, 1997Abstract. The effect of rate and timing of autumn/winter straw incorporation on the immobilization of spring‐applied N‐fertilizer are studied. The immobilization of 15 N‐labelled fertilizer by straw was determined in pot trials with a sandy loam soil (Wick series ...

Recycling rice straw by composting, incorporating and mulching
Conservation & Recycling, 1984Abstract Rice straw is rich in nitrogen, potassium, carbon and silicon. It is, however, seldom put to agronomic use by farmers in Sri Lanka, mainly owing to lack of awareness of the quantity of plant nutrients present and lack of simple and inexpensive methods of recycling.

Response of soil microbial biomass to straw incorporation
Journal of Soil Science, 1988SUMMARY The response of the soil microbial biomass to cereal straw incorporation was assessed for three sites in Eastern Scotland. Increases in the C:N ratio of the biomass, due to straw inputs, were greater for soil with a history of straw incorporation than soil with no previous incorporation history.

Incorporation of Straw with Grass at Ensilage
Journal of Agricultural Engineering Research, 1998Abstract In two experiments (Experiments 1 and 2) conducted over a two-year period, straw was incorporated with grass at ensiling, as a single layer of bales over the floor of a bunker silo and mixed as layers of loose straw sandwiched between layers of grass throughout another silo.

Straw incorporation induces rice straighthead disease in As-contaminated paddy soil
Science of The Total Environment, 2023Rice straw incorporation is globally recognized as a viable alternative to incineration. However, it might lead to arsenic (As) methylation in soils, resulting in increased accumulation of methylated As in rice plants, potentially contributing to the emergence of rice straighthead disease.

A field experiment was conducted over four seasons on a clay loam (24% clay in topsoil) in Scotland. Straw incorporation with conventional ploughing, shallow ploughing, rotary and tine cultivation was investigated for continuous winter barley. Residue treatments were either chopped straw plus stubble or stubble only.
