Intensively land use for biomass production without applying sustainable and sustained plant farming technique in District Selo potentially causes soil damage. Determination of soil potential damage and soil damage status has been set by the central government through Government Regulation No. 150 year 2000 on Soil Damage Control for Biomass Production. The research method used was a descriptive survey with a stage-setting soil potential damage by overlay thematic maps and the determination of the status of soil damage using matching methods and relative frequency score. Results obtained in the land area of the District Selo potentially medium damage 1,439.3 hectares and 1,988.8 hectares of high potential damage. After survey and laboratory analysis of soil samples at the site results that the Status of Soil Damage categorized light (R.I) with a score relative frequency of each 8. Total area that included minor damage divided into 3,296.97 hectares with limiting factors texture and permeability and 59.32 hectares with limiting factors permeability.

This research conducted to determine the exact formula and dosage to increase the uptake of N and increase yield of green mustard. The research conducted at Jumantono dryland research center, Karanganyar and Laboratory of Chemistry and Soil Fertility, Faculty of Agriculture UNS Solo. This study uses a randomized complete block design (RCBD) using 5 formulas as the first treatment factor and 4 dosages as second treatment factor. The data analysis used F test level of 5% and if significant continued by DMRT (Duncan Multiple Range Test) level of 5%. The variables of this research were weight of wet stover, weight of dry stover, N total and absorption of N. The results showed that the combination of dosage and formula of natural fertilizers can increase N uptake and yield of mustard on the ground Alfisols.

Erosion is the main factor causing land degradation in area of planting vegetables dominated by Andisol soil. Andisol soil contains more fraction of dust so it is easily transported by runoff. This study aim to determine the influence of mulching corn stem with a terrace strengthen (Vetiveria zizanioides, Coix lacryma-jobi L., Panicum muticum, Annona squamosa) to surface runoff, erosion, growth and result of plant (red lentils, cabbage and white lentils) in Andisol soil. This study uses a randomized complete block design with four (4) treatment and repeated three (3) times as a group so that there are twelve (12) experimental unit. The grouping based on kinds of plant that are cabbage, red lentils and white lentils. The results showed that MS4 treatment (mulch corn stem twelve (12) ton/ha with panicum muticum+ Annona squamosa as terrace strengthen) produces smallest of surface run off, erosion and dry weight of weeds, increased growth and canopy and increased crop yields 40.27% of red lentils, 57.10% of cabbage and 14.54% of white lentils.

Land used in agriculture plays an important role in supporting the production of biomass. Destruction of land for biomass production is changing the nature of the soil that exceeded the standard criteria of soil damage. Mapping of land degradation status is useful to know the condition of the soil and tillage correct action. This study was conducted using a survey in the Subdistrict Cepogo Regency Boyolali. Existing data will be scoring and macthing with standard criteria for biomass production ground damage that Government Regulation No. 150 of 2000. Analysis of the data shows that there is no damage land area covering 744,1 Ha (13,7%) and there are areas relatively lightly damaged by parameters of degradation status, namely the composition of the fraction covering 494,4 ha (9,1%), the degree of release of water parameters covering 294,4 ha (5,4%) and a combination of parameters fraction composition and the degree of release of water covering 1.813 Ha (33, 4%).
