Title: The Different Fertilizer Application on Thin Layer Black Soil Nutrition and Maize Yield
Abstract: Aim at the issues of the low soil organic matter concentration and soil nitrogen reserves and descending yield potential which caused by serious soil erosion in black soil area of northeast China, field experiments were applied to study the effect of NPK fertilizer combined organic manure on soil organic matter concentration and nutrient concentration in the Xingmu Erosion and Environment Research Station in the Soil and Water Conservation Institute of Jilin Province. The results showed that NPK fertilizer combined cattle ordure was better than NPK fertilizer combined corn straw with equal nutrient quantity. Compared with the control(with no fertilization), soil organic matter, total nitrogen, available nitrogen, available phosphorus, total potassium and available potassium significantly increased in 0 ~ 20 cm depth of soil(p 0.05). However, NPK fertilizer combined organic manure had little influence on the soil quality in 20 ~ 40 cm depth. Excessive organic manure could decrease the growth rates of soil organic matter and nutrition. Compared with the plot with only NPK fertilizer, yield could be increased to 14.51% ~ 33.03%(p 0.05). The inputs of corn straw and cattle ordure into soil should be 50% of the total production and 3.75 t hm-2, respectively.
