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.
Organic matter levels can be improved by manuring and/or by cover cropping with legumes or grass. This practice â with the residues used as a mulch â can also help improve soil structure, water holding capacity and moderate soil temperatures. Citrus prefer well-drained soils with a pH of 5.5 to 7.0 and low salinity. Yields are almost halved when pH drops to 4.5. Soil pHs can range from 4.5 to 9.0 and this has a distinct impact on the availability of certain nutrients. Extreme soil pHs should be adjusted where it is practical to do so.
