Effects of different land consolidation methods on soil properties of cultivated land

As an important reserve cultivated land resource in my country, its development and utilization are of great significance to ensure food security. Aiming at the problems bare gravel leakage shallow soil layer barren rock beach area, through community simulation experiments, different covering structures were set up on basis underlying gravel, effects physical chemical properties crop yield monitored obtain Find suitable structures. The results show that: when thickness is 60cm, content total nitrogen available phosphorus reaches maximum; bulk density 1.5 g/cm 3 , maximum. potassium increased with increase density.
