Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate . Additional chemicals vary depending on the mineral source and may include calcium oxide .
Dissection of grape tomato with blossom end rot. Calcium deficiency can sometimes be rectified by adding agricultural lime to acid soils, aiming at a pH of 6.5, [10] unless the subject plants specifically prefer acidic soil. Organic matter should be added to the soil to improve its moisture-retaining capacity. [10]
Amelioration of soil structure leading to a reduction of mineralization by means of protecting soil organic carbon. Liming is known to ameliorate soil structure, as high Ca 2+ concentrations and high ionic strength in the soil solution enhance the flocculation of clay minerals and, in turn, form more stable soil aggregates.

Greenhouse tomatoes are a crime against humanity.Ask any foodie — the ideal tomato is grown outdoors in the finest soil; it matures throughout the early and midsummer, just in time for harvest ...
In tomatoes, the stems are woody and growth is slow. Leaves are blue-green in color, and the interveinal area often fades to a pale gray color. Leaves may also have a bronzed appearance and yellow and orange patches may develop on some of the leaflets. Fruits often ripen unevenly and sometimes have green patches near the stalks.
Iron deficiency can be avoided by choosing appropriate soil for the growing conditions (e.g., avoid growing acid loving plants on lime soils), or by adding well-rotted manure or compost. If iron deficit chlorosis is suspected then check the pH of the soil with an appropriate test kit or instrument. Take a soil sample at surface and at depth.
Tomatoes grown in this manner produced about double the yield of tomatoes grown alone - or "monocropped" - in the same simulated Martian soil, with more and bigger fruit.
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
