The bidriware is now ready for the final blackening process. Traditionally, the craftsmen of Bidar use soil taken from the grounds of a 15th century fort in Bidar, which is rich in potassium nitrate. [6] The soil is mixed with ammonium chloride and water to produce a paste which is then rubbed onto a heated brass surface. The paste darkens the ...
The potting mixes are used to grow different types of plants depending on their nutrient requirements. [1] All three potting mixes have the same soil component: 7 parts sterilised loam; 3 parts peat; 2 parts sharp sand [5] They each contain ground limestone, and varying quantities of the same base fertiliser mix: 2 parts hoof and horn; 2 parts ...
A soil test may be done to analyze the chemistry of a potting mix, despite the mix not necessarily being made of soil. As an approximation for indoor home planting, the mix is generally treated as greenhouse growth medium. The main method is a saturated media extract (SME), which tests the chemical contents of a water extract of the mix. [13] [15]
Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in an artificial environment.
Reuse of wastewater in agriculture is a common practice in the developing world.

Compost from animal manure and composted household waste are applied by many farmers as soil conditioners.

Where the native soil is heavy or sticky, gentle mixing of vermiculite as a soil conditioner—up to one-half the volume of the soil—is recommended. This creates air channels and allows the soil mix to breathe. Mixing vermiculite in flower and vegetable gardens or in potted plants will provide the necessary air to maintain vigorous plant ...
Abstinence from soil tillage before planting and leaving the plant residue after harvesting reduces soil water evaporation; It also serves to prevent soil erosion. [ 119 ] Crop residues left covering the surface of the soil may result in reduced evaporation of water, a lower surface soil temperature, and reduction of wind effects.
