Randeep replied | 17 Jun

no,wheat is a KHARIF CROP.. bcz i agree it is grown in the winter season but guys do tell me this thing that the wheat crop ripens only when the temperature rices and we know that temperature rises only when its the end of winter season ans starting of summers. so, the wheat crops ripen during that time and hence, we can definetely say that wheat is a kharif crop rather than saying its rabi crop.

Loamy soil, a relatively even mix of sand, silt and clay, feels fine-textured and slightly damp. It has ideal characteristics for gardening, lawns and shrubs. Loamy soil has great structure, adequate drainage, is moisture retaining, full of nutrients, easily cultivated and it warms up quickly in spring, but doesn't dry out quickly in summer. Loamy soils require replenishing with organic matter regularly, and tend to be acidic.

Great for: Climbers. bamboos, perennials, shrubs and tubers such as Wisteria, Dog’s-tooth violets, Black Bamboo, Rubus, Delphinium. Most vegetable crops and berry crops will do well since loamy soil can be the most productive of soil types. However, loamy soil requires careful management to prevent depletion and drying out. Rotating crops, planting green manure crops, using mulches and adding compost and organic nutrients is essential to retain soil vitality. «less

The soil's ability to retain water is strongly related to particle size.Clay soil has small, fine particles, which is why it retains the most amount of water. Sand, with its larger particles and low nutritional content, retains the least amount of water, although it is easily replenished with water. Silt and loam, with medium-size particles, retain a moderate amount of water.
