- •
Paddy soils under long-term fertilization are used to examine puddling resistance and shrinkage capacity.
- •
Mineral and no fertilization had no effects on aggregate stability and shrinkage capacity.
- •
Organic amendment increases the resistance to water slaking and puddling.
- •
Organic amendment increases the shrinkage capacity of puddled soil.
- •
Intensive puddling and extreme drying destroy the macro and mesco pores and then shrinkage capacity.
