The results showed that the best organic fertilizer application patterns in Fuji apple orchard were NPK + wheat straw compost and NPK + sheep manure application under irrigation, the yield were 38 500 kg/hm and 38 050 kg/hm2 respectively and the yield increased by 32.

Effects of different nitrogen fertilization patterns on the quality of the lettuce and soil environment;

Based on a long -term located field e xperiment,risk of different fertilization models in rice field on water environment pollution in a sloped red soil was ass essed by using ceramic tubiformsoil solution collectors.

Two filed experiments located at the south edges of the Loess Plateau were used to study the effects of different cultivation and fertilization models on contents of SMBC,SMBN,SOC and SON in soils.

Effects of different fertilization modes on vegetable growth,fertilizer nitrogen utilization,and nitrogen loss from vegetable field

Under the condition of natural rainfall, through three-stubble vegetable’s field trials in one year, 7 different kinds of fertilization modes (i.
