Sufficient Level of Available Nutrients (SLAN) versus Build Maintain Fertility Programs
It can be argued that SLAN and Build/Maintain can be similar in some ways, both making an application of fertilizer to keep soil test levels where they are and feed the crop to be grown. However, SLAN is geared more towards achieving a fertility level where maximum yield can be obtained in that year where Build/Maintain is trying to keep the soil test levels from dropping.
