I don't think petite is a height so much as a body shape. I have seen tall women shopping in the petite section because they have a short waist or shorter arms or wanted a skirt that fits them better than the regular ones, and I have seen smaller women shopping in the junior/misses/womens section for similar reasons.
Sweet clover needs a high pH, 6.0 or higher, for proper nodulation to occur, and it has a higher calcium requirement as well. Sweet clover is able to obtain phosphorus from relatively unavailable soil phosphates and will grow on soils where alfalfa, red clover or ladino will fail.
Clover stands should be fertilized annually according to soil test recommendations. In the absence of a soil test and assuming a medium-fertility soil, apply 0-60-145 lb. per acre. When white clover makes up less than 30% of a white clover-grass mixture, apply 30 to 50 lb. of N per acre to enhance grass production. White Clover Summary. White clover is a low-growing forage legume which is predominantly used in pasture mixtures with grasses.
