Advance Sowing (also known as "no kill cropping") dry-sowing crops directly into existing pastures without using tillage, fertilizer or chemicals.

C

C3 plants, such as wheat, rice, oats, and barley, grow early in the season and then become less active or go dormant as temperatures rise and light intensity increases.

C4 plants, such as corn, sorghum, sugarcane, and millet, remain dormant until temperatures become warm enough to switch on and begin growing.

Companion Planting: Placing plants from differnt species close to each other, so one benefits the other, for example by keeping away pests or insects. Cover Crops: are crops which are planted specifically with the aim of preventing soil erosion through dry out and suppress weeds.

Deep Ecology is a holistic worldview, which understands earth as a living system in which all is related. Thus it understands humans as embedded in the ecosystem, not superior to it.

Deep Adaptation is a concept based on the paper "Deep Adaptation: A Map for Navigating Climate Tragedy" written by sociologist Jem Bendell. It posits that the effects of climate change may be so extreme as to lead to civilizational collapse, and that instead of downplaying this conclusion, we should embrace it. A central theme is the notion of 3 R's: Resilience, Relinquishment, and Restoration.

Pasture cropping utilizes the niche created by C3 and C4 plants. When a C4 is dormant (during winter), a C3 plant seed is sown by no-till drilling into the C4 pasture. With the onset of spring, the C3 plants begin to grow. If managed properly, plus the right amount of rain, the C3 crop can be harvested before the C4 plants begin the vigorous part of their growth cycle. The removal of the C3 crop will then stimulate C4 plant growth (due to reduced competition). The mix of shallow- and deep-rooted plants also access water resources in the soil differently, which can reduce competition and increase overall productivity.

Perennial (per- + -ennial, "through the years") is a plant that lives more than two years. The term is also widely used to distinguish plants with little or no woody growth from trees and shrubs, which are also technically perennials.
