| Abstract: | The effects of different fertilizer application ways on crop yield and soil fertility were studied based on a 29-year located fertilization field experiment in dark-brown soil farmland system in Heihe city,Heilongjiang province of Northeast China.The results showed that there is great difference in crop yield and the content of soil nutrients between different fertilization treatments,especially for a combination of organic and chemical nitrogen and phosphorus fertilizers which played an important role in i... |
