Abstract

Planted corn by intensively made decreased soil health and decreasing soil capacity to support plant growth caused of nutrient is not available, poor microbial activity, increasing soil acidity and soil crusting. If this problem do in long term, it will make decrease soil reciliency and decrease plant producitvity. This research was aim to investigate of soil health assesment with cornell method on some plant pattern by corn at Kenagarian Mungka. This research used explorative descriptive method through land survey and soil analyses in the laboratory. The samples were taken based on purposive random sampling. There were three land unit planted by corn with plant pattern are monoculture corn, corn-eggplant and corn-cassava. Each selected soil indicator scoring to discover the soil health correlation test to know relation between parameter with soil health.This research showed that Mungka’s land unit  planted by corn have moderate-high category for soil health, monoculture corn had the highest soil health by 65.96, corn-cassava had soil health value by 63.94 and the lowest is corn-eggplant with 63.35 soil health value. This research used three component of soil those are soil chemical, biology, and physic. This research showed that some indicator have the significant determinant indicator for soil health are OM (r=0,9209), pH (r=0,9471), and respiration (r=0,6055). Farmer was do the addition of organic matter from poultry manure to the land regularly. Based on this research, organic matter is the most important thing to keep soil health especially to encourage corn productivity.

Abstract

Land continuously planted with corn will decrease land quality. Good land quality is needed to support soil function as a growing medium and keep a sustainable environment. This research was aimed to identify the soil quality index at land unit planted with corn in Mungka, ,Lima Puluh Kota Regency. This research used an explorative descriptive method through land survey and soil analyses in the laboratory. The samples were taken based on purposive random sampling at each land unit under the same slope (8%). There were three land units being sampled, and those were corn-corn, corn-eggplant, and corn-cassava cropping pattern. Corn-corn ropping pattern had the best soil quality index (0.89), followed by corn-cassava (0.86), and corn-eggplant (0.85) on the top 20 cm soil depth. On the 20-40 cm soil depth, the soil quality indices 0.82, 0.82, 0.83, for corn-eggplant, corn-corn, and corn-cassava cropping pattern, respectively. The quality index of the land under the corn cropping pattern was considered good either on the top 0-20 cm or 20-40 cm soil depth. This was due to the addition of organic matter from poultry manure to the land regularly. Based on this research, it is recommended to apply OM regularly to corn cropping pattern to keep a good soil quality index.
