The meteorite is named after the small nearby town of Pueblito de Allende (shown as Allende on the map). Like many meteorites, The Allende entered the atmosphere and friction began to heat it up. The main mass of the meteorite exploded and the fragments fell over the area shown as the "Allende strewn field." (If you use a Netscape web browser
Making Fertilizer Recommendations from Soil Test Reports Purpose
usually range from 10 to 200 ppm K. K is relatively abundant in Alaska soils, especially in the interior, and soil test levels are generally show adequate amounts of K in the soil for most crops. Calcium (Ca) - Calcium is essential in the proper functioning of plant
Coral Calcium: Hype or Highly Effective Supplement?
Calcium also has been shown to bind secondary bile acids in the colon, allowing acids to be excreted rather than being reabsorbed, which leads to faster gallstone formation. Countries (such as Peru, Sri Lanka and China) that have the lowest calcium levels in the diet have populations that maintain lifelong healthy bones, while Americans tend to have brittle bones.

Granite - Wikipedia
Granite (/ ˈ ɡ r æ n ɪ t /) is a coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.It is common in the Earth''s continental crust, where it is found in various kinds of igneous intrusions.

Crop Guide - Nutrients for Cucuer - Haifa Group
Treatment of calcium deficiency Applying lime to acidic soils and reducing the use of ammonium-based fertilizers is recommended to avoid insufficient calcium availability in the soil. Existing injury from calcium deficiency can be reduced by regular foliar sprays of fully soluble calcium nitrate, (15.5-0-0+26.5 CaO), e.g. Haifa Cal, at 800g / 100L).
Acid Rain - USGS
Acid rain also removes important nutrients from the soil, such as calcium, potassium, and magnesium. The lack of nutrients can negatively affect the health of plants and animals. Lastly, the coination of reduced calcium and excessive aluminum can make forests more susceptible to pests, disease, and injury from freezing and drought, as a proper balance of these nutrients is vital to forest

Using a quadrupole inductively coupled plasma mass spectrometer (Q-ICP-MS), the concentrations of the following elements in the soil extract were recorded in parts per million (ppm): aluminum (Al), barium (Ba), calcium (Ca), iron (Fe), potassium (K
Feldspars--calcium, sodium. aluminum silies--are the most important rock forming minerals in the crust of the Earth, but are relatively scarce in meteorites. There are two main groups of feldspars, plagioclase and orhtoclase. Each group is broken down into

Limestone - an overview | ScienceDirect Topics
It is also important to assess calcium and aluminum concentrations in deeper layers. Limestone applied to correct acidity in the arable layer (0–20 cm) moves slowly to the subsurface layer (20–40 cm) depending on soil type, rainfall and irrigation, dosage, elapsed time, and subsequent fertilization.
Limestone - an overview | ScienceDirect Topics
Three samples contained 3.6, 3.9 and 8.4 mg Cd kg −1 dry weight, and 2500, 2810 and 4580 mg Zn kg −1 (Cd:Zn ratios are 0.00156, 0.00139 and 0.00173, all far below the ratios of ores and fertilizers). Normal agricultural limestone contains <0.3 mg Cd kg −1 and 21 mg Zn kg −1.
The Snorkel® and Scuba® Stoves
We precision-cut marine grade aluminum with plasma cutting machines, then form our stoves using high-tech bending equipment and hand-weld every seam. More importantly, we powder coat each stove because many water supplies contain concentrations of minerals like calcium and magnesium that will corrode even the highest quality metal alloys if they’re not protected.
Road Dust Control with Calcium Chloride
Aluminum and its alloys must not be used in spreading equipment, as they deteriorate rapidly upon exposure to calcium chloride. Explosion- proof equipment may also be desirable when large amounts of calcium chloride dust are present cium chloride
