Effect of Different Fertilization Patterns on Losses of Soil, Water and Nitrogen, Phosphorus from Tea Garden in Eastern Fujian Province
[Objective] The effect of fertilization patterns on losses of soil
water and nitrogen
phosphorus from tea garden in eastern Fujian Province was studied in order to provide a scientific basis for evaluation and prevention and control of soil and water loss in this region. [Methods] The experiment contained six treatments: no fertilization(CK)
chemical fertilizers(NPK)
half-organic manure plus half-chemical fertilizers(1/2 NPKOM)
organic manure(OM)
legume stover returned plus chemical fertilizers(NPKL)
half-organic manure plus legume stover returned plus half-chemical fertilizers(1/2 NPKOM+L). [Results] Among all the treatments
water losses were ranked as OM > 1/2 NPKOM > NPKL > CK > NPK > 1/2 NPKOM+L
and soil losses followed the orders of OM > 1/2 NPKOM > NPKL > CK > NPK > 1/2 NPKOM+L. Furthermore
the OM treatment had maximum concentrations of soil nutrients including total N (TN)
dissolved N (DN)
NO3-N
NH4+-N
total P(TP) and dissolved P(DP) losses in runoff
while the 1/2 NPKOM+L treatment had minimum concentrations of those nitrogen and phosphorus fractions compared to other fertilizer treatments. Similarly
the contents of TN
TP in sediment were the highest in OM treatment
but the lowest in 1/2 NPKOM+L treatment. [Conclusion] The 1/2 NPKOM+L treatment could be considered as a better choice of fertilization practice with respect to reducing soil
water
and nitrogen
phosphorus nutrient losses from tea soils in the region.
