摘要: Study on phosphorus and potassium balances of cabbage at different soil conservation techniques was conducted in Talun Berasap, a vegetables growing area Kerinci District, Indonesia 2011. Four treatments were tested including control, farmers practices with the direction planting line slop (KTA-1), modification farmer practice by adding ridge terrace every 5 m slope length (KTA-2), hill side ditch (KTA-3), (4) contour (KTA-4). Phosphorus calculated according to differences between gains losses. To quantify total inputs, P K contents SP-36 KCl, rate compost, concentrations as well rainfall collected. Output parameters yield, crop residues production, erosion. The results indicated that positive taken place all treatments. Concerning environmental, agronomical economic point views get higher yield stabile, recommended application should be 100 kg 50 KCl ha season more compost up 20 30 tons season.
