Evaluation of Land Capability in Critical Land Das Welang, Pasuruan Regency, Indonesia

Nowadays the watershed in Indonesia continues to experience degradation caused by the management of natural resources in it which is quite aggressive, exploitative, and expansive that exceeds the carrying capacity and capabilities. The objective of this research is the mechanism of land capability in describing the distribution of critical land agriculture in the Welang watershed in a comprehensive and integrated manner. Analysis of soil samples after being dried is carried out in the laboratory so as to obtain quantitative figures both physical, chemical, and biological soil properties. Determination of research survey points taken at the critical critical level level, somewhat critical to critical with the land use unit (SPL) of plantations, mixed gardens and fields on medium plains. The results of the study can be concluded that the coffee and mango plants become the dominant plants to be cultivated in the moderate land area, and for the moor, corn plants become the mainstay for cultivation even though based on the ability of the land to have classes that vary from III to VIII according to the characteristics of landforms ranging from sloping to steep also viewed from the actualization of the land showing the land in critical condition. The ability of the land produced from dai III to VII is in accordance with the characteristics of the landform from the sloping to steep. So that corn plants can still be planted for upland fields even though the level of soil fertility is low to moderate with limiting factors ranging from temperature, root media, nutrient retention, erosion hazards and land preparation. Provision of minimal organic matter and land management for land, making terraces is more recommended because to reduce the level of erosion even though some upland areas are not critical while those that are more critical require integrated handling in land management.
