PENENTUAN NILAI FAKTOR TANAMAN KACANG PANJANG DAN MENTIMUN DENGAN METODE PETAK KECIL DAN USLE PADA TANAH ANDEPTS DI KEBUN KWALA BEKALA USU
ABSTRACT: One way to overcome
erosion is using vegetative methods, where its influence can be manifested by
the C factor. The best C factors used in determining the amount of erosion is
the value of C in the local area. This study was aimed to determine the value
of string bean and cucumber crop factors on the Andepts soil during April to
August 2013 using the method of small plots and USLE. Parameters used in
determining the C factor were the amount of erosion, the allowable erosion
rate, and the erosion hazard level. The results showed that the amount of
erosion on land without a crop was 0,46 ton (ha.year)-1,on cucumber land was
0,41 ton (ha.year)-1, on string bean land was 0,31 ton (ha.year)- 1. The amount
of allowable erosion
rate was 31
ton (ha.year)-1 . While
erosion hazard rate
on land without
a crop was
0,014; on cucumber land was 0,013
and on string bean land was 0,010 which include in low category. The value of
string bean crop factor using rainfall research data for 4 months and 10 years
data was 0,685 and 0,690 respectively. The value of cucumber crop factor using
rainfall research data for 4 months and 10 years data was 0,902 and 0,911
respectively
