Ping Xie Journal of Soil and Water Conservation 2013
Other claims from this paper (10)
- Intervention effect Chemical fertilizer decreased soil pH.
- Intervention effect Adding manure to chemical fertilizer relieved soil acidification and significantly increased SOC and available nutrients.
- Intervention effect N fertilizer alone reduced maize kernel, cob, straw and root amounts relative to CK.
- Intervention effect Balanced fertilization increased maize biomass components 1.1 to 2.9 times relative to CK.
- Intervention effect Organic fertilizer increased maize biomass components 1.1 to 2.9 times relative to CK.
- Observation Maize nitrogen was mainly in kernels, at 41.8% to 61.3% of total crop N.
- Observation Maize nitrogen in straw accounted for 30.3% to 48.4% of total crop N.
- Observation Kernel phosphorus was highest, at 61.8% to 73.9% of total crop P.
- Observation Potassium content was highest in straw, accounting for 51.4% to 67.9%.
- Intervention effect Combined chemical and organic fertilizers promoted nutrient uptake and maize yield.
