Effects Of Soil Amendment Fertilizer On Soil Moisture,Nutrient And Crop Yield

In this study,organic and inorganic compound soil amendment fertilizer developed by the organic shale,oil residue and chemical fertilizers was used to compare the effects of different amounts of soil amendment fertilize,soil amendment material and traditional fertilization?only chemical fertilizers?on crop yield,water use efficiency,content of topsoil soil organic matter,distribution of inorganic nitrogen and water content in soil layer of 0-160 cm by field experiment.The main results were as follows.?1?In wheat and maize season,fertilization treatment can significantly improve the surface soil moisture,the addition of soil amendment material has a positive effect on the improvement of surface soil moisture.Fertilization can significantly enhance the water content of 0-100 cm soil layer,reduce the soil water content of 100-160 cm soil layer,reduce effectively the loss of soil water from the upper layer to the deep one,it is better to provide a suitable water and soil environment for crop growth,the addition of soil amendment material has a positive effect on the improvement of the soil water content in the 0-160 cm soil layer.During the whole growth period of wheat and maize the dynamic analysis of 0-160 cm soil water storage was obtained,soil reservoir of wheat shows “water expenditure”,soil reservoir of maize shows “water revenue”.Fertilization can enhance the storage capacity of soil reservoir,the addition of soil amendment material has a positive effect on the improvement to enhance the storage capacity of soil reservoir.?2?NO₃^--Ncontent was greatly affected by nitrogen application rate,the higher nitrogen content,the higher3 NO N--content,the addition of soil amendment material has a positive effect on the improvement of3 NO N--content.The treatment with less than154.7kg/hm2 of nitrogen can basically control the leaching of nitrate nitrogen into the deep soil in the surface soil,which can reduce significantly the risk of3 NO N--leaching to groundwater.The amount of nitrogen applied to the soil in the 0-160 cm soil layer has a great influence on accumulation of3 NO N--,the higher nitrogen content,the higher accumulation of3 NO N--,the addition of soil amendment material has a positive effect on the improvement of accumulation of3 NO N--with high nitrogen level.Different fertilization treatments have no significant effect on4 NH N?10?-content and accumulation.Fertilization can reduce soil p H,soil amendment fertilizer is helpful for delaying soil acidification.Both the treatment of organic fertilizer and the application of organic and inorganic fertilizers canincrease the content of soil organic matter,soil amendment fertilizer is more significant.Adding soil amendment material but no fertilization has little influence on increasing soil organic matter.?3?The effects of traditional fertilization and soil amendment fertilizer on crop yield,straw yield and aboveground biomass yield are significant,soil amendment fertilizer 3?1125.0kg/hm2?is the best effect on increasing wheat yield,but the best treatment is soil amendment fertilizer 2?937.5kg/hm2?for increasing maize yield.In the range of fertilization,with the increase of the application rate of soil amendment fertilizer,crop grain yield,straw yield and aboveground biomass also increasing.Fertilization can improve the use efficiency of water.Compared with other fertilization treatment,soil amendment fertilizer treatments has the best effect on increasing the use efficiency of water.The water use efficiency of soil amendment fertilizer 3 is the highest in wheat season but amendment fertilizer 2 in maize season.
