Effect of Soil Damage on Carrying Capacity of Biomass Production: A Lesson from Tanjung Selor District – Tanjung Redeb, Indonesia

Currently, land use is considered intensive for various purposes that affect the soil as main series of and environment. The other side in Kalimantan naturally formed from material poor nutrients so it not fertile acidic. This study attempted to evaluate status damage carrying capacity biomass production Tanjung Selor District. overlay analysis slope, rainfall, type cover form a map produces indicative areas low, medium high damage. High were selected verification, observation sampling obtain parameter data, carried out March 2020. Analysis relative frequency score damaged parameters aims determine results based on 10 obtained 6 with lightly damage, factor being acidity (R.I-a) 1,684 ha. pH <4.5 (very acidic) has most effect, 80% damaged, but relatively easy repair. Efforts improve cultivated plants are stressed by using amendments raise above minimum range more suitable increase capacity, namely agricultural lime compost followed N, P K fertilization needed.
