Dynamics of soil fertility and maize growth with lower environment impacts depending on a combination of organic and mineral fertilizer

Abstract: The combined application of organic and mineral fertilizers is gaining recognition as a viable approach to address the decline of soil fertility in intensive cultivation. A four-year experiment was conducted to study the dynamics of maize growth and analyse environmental changes. Two treat...

A four-year experiment was conducted to study the dynamics of maize growth and analyse environmental changes. Two treatments were designed, (І) mineral fertilizer treatments (MF) that received the optimal fertilization level with 185 kg N/ha, 60 kg P2O5/ha, and 90 kg K2O/ha and (П) the combination of organic and mineral fertilizer treatments (OMF) with the application of 3.75 t/ha organic fertilizer supplemented with 125 kg N ha-1. The results indicated that OMF could improve the maize yield by 9.7-13.6 %, while the aggregate environmental index was reduced by 17 % compared with MF. Principal component analysis (PCA) showed that OMF promotes maize growth and yield attributed to the increased N, P and K uptake at the 12-leaf stage and tasseling stage, and the increased urease activity and P uptakes at the harvest stage. Life cycle assessment (LCA) analysis indicated that OMF decreased energy consumption, greenhouse gas emissions, acidification and aquatic eutrophication compared with MF. The results clearly revealed that organic applied with less mineral fertilizer had a higher maize yield and lower agricultural environmental risk compared to only mineral fertilizer.info:eu-repo/semantics/openAccessChilean Society of Soil Science / Sociedad Chilena de la Ciencia del SueloJournal of soil science and plant nutrition v.18 n.2 20182018-06-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-95162018000200556en10.4067/S0718-95162018005001701
