what is a method of planting crops that disturbed the soil and its plant cover as little as possible called?

There are two principal approaches to planting crops: direct seeding and transplanting. Direct seeding can be done by broadcasting, hill or dibble planting, or by drilling; the hill and drill techniques are alternatives for row planting. Direct seeding, or direct sowing, means putting seeds straight into the field or another growth medium, while transplanting uses seedlings, pre-grown plants, or vegetatively propagated material. Transplanting can also mean moving an established plant from one spot to another. Direct seeding is typically used for large-seeded vegetables as well as cereals and grain legumes. Transplanting is commonly applied to small-seeded vegetables, vegetatively propagated crops, ornamentals, fruit trees, and many perennials. The phrase direct seeding can also refer to placing seedpieces or underground vegetative planting material directly into the soil. Broadcast, Hill, and Drill Methods of Planting Distinguished Broadcasting, or sabog tanim (scatter planting), is usually used for small seeds such as rice and mungbean that can germinate and grow without being covered by soil. This method does not control spacing between plants. Seeds are spread over a well-prepared seedbed by hand or with a mechanical broadcaster. With hand broadcasting, seeds are held in the hand and cast over a wide area. Skill is required to achieve an even seed distribution per unit area consistent with the intended seeding rate per hectare. For instance, a seeding rate of 100 kg per hectare requires distributing on average 0.01 kg or 10 g per square meter. If the crop is rice with a 1000-grain weight of 29 grams, this corresponds to about 345 seeds per square meter. Planting too densely means the available seeds will be used up before the entire field is covered, requiring more seed. Planting too sparsely results in finishing the field while still having seeds left over.
