Calcium carbonate, the chief component of limestone, is a widely used amendment to neutralize soil acidity and to supply calcium Ca for plant nutrition. Limestone is a common sedimentary rock found in widespread geologic deposits. It has been used throughout much of recorded history as a building material, a cementing agent, and in agriculture to improve acid soils. An agricultural liming material ag lime is broadly defined as any substance containing Ca or magnesium Mg and capable of neutralizing acidity. Many materials can be classified as ag lime.

How to Add Calcium to Soil
More Information ». Jun 29, Print. Blossom end rot is a troubling disorder of tomatoes that affects home gardeners and commercial growers alike. Numerous foliar calcium sprays are available that claim to solve this problem, but are they really the answer? Blossom end rot is a common disorder affecting both home gardeners and commercial growers. In addition to tomatoes, blossom end rot can affect peppers, watermelon, eggplant, squash, and cucumbers. Blossom end rot is the result of a localized calcium deficiency in the fruit; however, this may not necessarily indicate a calcium deficiency in the soil or in other parts of the plant.
Blossom end rot can occur even when calcium levels in the soil are adequate. Calcium is highly mobile in plants, and a consistent supply is needed during fruit set for the fruit to develop properly. This requires an adequate supply of water in the soil. If the supply of water taken up by the roots is interrupted, the supply of calcium is also interrupted. Calcium that is present in leaves is not able to move through the phloem into the fruit.
In addition, the skin of the fruit is not able to directly absorb foliar-applied calcium. As a result, foliar calcium sprays are not effective. The most effective way to prevent blossom end rot is to maintain uniform soil moisture.
In other words, avoid allowing the soil to dry out in between watering. Setting up a drip irrigation system on a timer is a great way to ensure consistent watering. To reduce moisture evaporation from the soil, apply a layer of mulch or pine straw around the plants. Also, avoid damaging roots by hoeing or tilling near established plants, as doing so may reduce their ability to take up water.
Take a soil test well before planting and follow the lime and fertilizer recommendations to ensure appropriate levels of calcium are present.

Gardening Myths: Fix Blossom End Rot with Calcium Sprays
Calcium nitrate is a white to light grey, inorganic, granular solid. It has uses in agriculture and horticulture, waste water treatment, the manufacture of explosives and is used in a variety of industrial applications. In agriculture and horticulture, calcium nitrate is a popular inorganic fertiliser where soil acidification is unwelcome and when calcium and nitrogen are required to be supplied at the same time. It can be applied as a solution for rapid uptake or as side or top dressing to high value crops where its hygroscopic nature allows it to easily dissolve when on contact with soil in damp conditions. When used, calcium nitrate works to neutralise acids, promote cell growth and boost development.

Calcium Nitrate For Horticulture And Floriculture
In this edition of our series on nutrients for horticultural crops, we focus on calcium Ca. This is the fourth article in this series, after nitrogen N , phosphorus P and potassium K. Calcium is an essential nutrient for all crops.But it is a difficult element, both in terms of uptake and distribution in the plant. Calcium uptake is influenced by transpiration, the presence of other positively charged nutrients in the root environment i. Calcium has a strengthening effect on the cell membranes, just like the trace elements copper Cu and boron B. Calcium uptake is a passive process, which means that it enters the roots with the water flow. It is then transported up through the xylem dead cells to the parts of the plant that are actively transpiring.
Friday, September 24, Troy Buechel. Along with magnesium and sulfur, calcium is one of the three secondary nutrients. Like primary nutrients nitrogen, phosphorus and potassium , those elements are essential for healthy plant growth. However, they are needed in lesser amounts. Calcium, in the form of calcium pectate, is responsible for holding together the cell walls of plants.

LNT stress significantly increased the non-regulatory quantum yield of energy dissipation [Y NO ], whereas CaCl 2 alleviated this increase. LNT stress caused excess formation of a proton gradient across the thylakoid membrane, whereas CaCl 2 pretreatment decreased the said factor under LNT. Thus, our results showed that photoinhibition of LNT-stressed plants could be alleviated by CaCl 2 pretreatment. Our findings further revealed that this alleviation was mediated in part by improvements in carbon fixation capacity, PQ pools, linear and cyclic electron transports, xanthophyll cycles, and ATPase activity.

Hypocalcaemia is the most common calcium disorder of ewes and is frequently seen at lambing time. It also occurs in transported sheep and in other stressful situations, such as when yarded for shearing in winter. Fortunately, if recognised early, a simple treatment with a calcium solution injected under the skin and oral supplements will effect a recovery in most sheep. Other calcium disorders include osteomalacia in lambs and osteoporosis in ewes. Why are ewes so susceptible to hypocalcaemia and osteoporosis? During pregnancy and the first few weeks of life, the lamb is entirely dependent on the ewe to provide calcium to build strong bones. The peak demand for calcium by the lamb is at 10 days of age, but that demand on the ewe steadily increases from midway through pregnancy, as the lamb's bones begin to calcify.

Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen N , phosphorus P and potassium K. Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur. Plants also need small quantities of iron, manganese, zinc, copper, boron and molybdenum, known as trace elements because only traces are needed by the plant. The role these nutrients play in plant growth is complex, and this document provides only a brief outline.
Limestone, coal and atmospheric nitrogen are the natural raw materials from which calcium cyanamide is manufactured.

Calcium in crops plays a key role in agricultural development. Its existence guarantees firmer fruits. Agricultural calcium is necessary not only in structural strengthening of walls but also in the elasticity of the vegetal tissue. It is essential to have resistant and healthy plants.
