Agro-ecological suitability classification of selected crops in Laguna [Philippines]
1986
Monsalud, F.C.
hSuitability of each crop to a given soil and growing period zone was determined using the predicted yield. The predicted yield, the product of the potential yield of crop and the soil productivity rating, was classified into one of the four classes (very suitable, suitable, marginally suitable and not suitable) defined in terms of a percentage range of the maximum potential yield attainable within the study area. Annual crops such as peanut, mungo, cowpea, soybean, upland rice, sweet potato, cassava, corn and sorghum were suited in soils which were generally well-drained, with clay loam surface texture and with relatively high base saturation like Lipa clay loam, San Manuel clay loam, Macolod clay loam, Quingua clay loam, Macolod clay loam-steep phase, and paste clay. These soils were found not suited for sugarcane, coconut, banana and cacao. Soils which were marginally suitable for annual crops and not suitable for crops with longer maturity period have one or more limitations. Those soils classified as unsuitable for all crops possess higher degree of limitations than the marginally suitable gr
