Ammonium Sulfate provides a fast-acting source of nitrogen and sulfur. It can be applied in granular form via side-dressing, or as a liquid formulation through injection. Side-dressing should be followed by a light cultivation so that the fertilizer is incorporated into the top couple inches of soil.

This is enough fertilizer to feed 10,000 to 12,000-Christmas trees for a year. Clearly, the most important aspect of applying fertilizer to the trees at Shady Pond is the calibration of the spreader. Too much fertilizer will damage, or even kill the plants; too little will not produce the intended effect.

Calculate a conversion ratio by dividing 100 by the N% in ammonium sulfate (100/21 = 4.8). This ratio is the reciprocal of the N%. Multiply the first number (N/tree) times the second number (conversion ratio) to get the amount of ammonium sulfate per 5" tree (0.5 lb N/tree x 4.8 = 2.4 lbs. ammonium sulfate/5" tree).

A liquid solution of ammonium sulfate (21-0-0-24), providing 150 lb N/acre, was applied on March 26, 1991 (Figure 4). The fertilizer solution contained a stable, non-radioactive isotope of N that could be used to trace the movement of N into trees and through soil.

Fertilize Douglas-fir aristmas trees with N according to Table 3. Monitor foliar N to determine need for N fertili- zation. Refer to foliar sampling section for sampling insa-uctions. One type of nirogen fertilizer generally is not superior to another. In western Oregon and Washington, urea and ammonium sulfate. along with blends of the two,

Thereof, what is the best fertilizer for Christmas trees? Commercial N fertilizers commonly used for Christmas trees include urea, ammonium sulfate, and calcium nitrate. Of these materials, urea (46% N) is generally the least expensive N source. Use of urea fertilizer gradually lowers soil pH.

A: Ammonium sulfate is nitrogen and as such, has a big place in virtually all gardening we do. Grass, trees, shrubs, flowers, vines, vegetables and so on all use nitrogen. It is vital to their ...

Ammonium sulfate 21 . o o (75 lbs/ac) Results indicate a significant increase in height and basal diameter (Table II). Crown width and number of laterals were significantly increased by the use of sewage sludge. In a rating of the trees for color and marketability as Christmas trees the sludge treated trees …

Fertilizing your lawn with ammonium sulfate provides a quick-release boost for grass. Containing 21 percent nitrogen and 24 percent sulfur, and available as a granular and liquid feed, ammonium sulfate is a mineral fertilizer product suitable for cool-season and warm-season lawns. Its effects last four to six weeks.

ammonium sulfate, along with blends of the two, have been used with similar results. Ammonium nitrate, although used less commonly, should be equally effective. Fertilizer can be broadcast or applied to individual trees. The objective is to apply fertilizer evenly to the tree's root system. For small trees (i.e., less than 3 feet tall), fertilizer

Nitrogen (N) is usually the most limiting nutrient to tree growth. It is important for overall health and good color development. The soil test report recommends 100 to 120 lbs/acre of N, which is the standard recommendation for soils statewide. This rate equates to one ounce of N per tree, assuming a 5 ft. x 5 ft. spacing.

I am in Huntsville and have no issue finding Ammonium sulfate fertilizer everywhere. It's at Home Depot, Lowes, local seed & feed type stores, and my co-op. With that being said, it's usually a mixture of Ammonium Sulfate and some Urea so make it that 33-0-0 or 34-0-0 blend.

Ammonium sulfate fertilizer is a useful product when a soil foundation requires immediate improvement. Farmers and growers can support their seedlings when this product gets applied to their fields and gardens. With ongoing and careful tending, it is possible to produce higher yields, healthier plants, and stronger soil.

creation of nutrient imbalances; and 3) reduction in tree quality. Special attention should be given to the relationship between moisture availability and fertilizer effectiveness. Fertilization without vegetation control is counterproductive because weeds rob young trees of the water and growing space

To lower high pH several fertilizer sources are useful. Sulphur lowers pH but acts slowly, ammonium sulfate (21% N and 23% S), triple superphosphate, and diammonium phosphate are all acid forming fertilizers that supply additional nutrients while decreasing pH. When using the N source fertilizers, limit N to 20 pounds per acre per year ...

Dispersing granule technology in a homogeneous greens grade (75 SGN) fertilizer that breaks down quickly into the tightest turf canopies. This fertilizer is driven by methylene urea, ammonium sulfate, monoammonium phosphate, and potassium sulfate, providing 80% slow-release nitrogen that will feed for up to 12-16 weeks. Granular

A liquid solution of ammonium sulfate (21-0-0-24), providing 150 lb N/acre, was applied on March 26, 1991 (Figure 4). ... Using Fertilizers in the Culture of Christmas Trees. McEvoy, T.J. 1992. Paragon Books, Richmond, VD. Mineral Deficiencies of Coastal Northwest Conifers.

Ammonium sulfate is the most acidic material and can be used to make small reductions in soil pH while satisfying the nitrogen requirement. Calcium Nitrate contains a more soluble form of calcium that can be beneficial when Christmas trees are deficient in calcium and lime would be too slow-acting. ... For a perennial crop like Christmas trees ...

Fertilizers containing calcium should be flushed from all tanks, pumps, filters, and tubing prior to injecting any phosphorus, urea-ammonium nitrate, or urea sulfuric fertilizer. Calcium should not be injected with any sulfate form of fertilizer because it combines to create insoluble calcium sulfate, or gypsum.

Each species of conifer used as Christmas trees tends to put different demands on the soils ability to supply nutrients. While these differences are not always enough to require unique soil test fertilizer recommendations, Trees in different categories may respond differently to fertilizer programs, or to adverse conditions.

Ammonium can be held on the soil colloids, and will resist leaching while nitrate ion will be will be subject to rapid leaching. Common fertilizer materials used as nitrogen sources in Christmas tree production include; Ammonium sulfate (21-0-0-21) is a strongly acid-forming nitrogen fertilizer that is relatively easy to handle and provides sulfur.

Mature lemon trees' fertilizer needs vary according to the size and age of the trees. For example, small trees that have been in the ground for four years need 3/4 pound nitrogen -- 3 1/2 pound ammonium sulfate -- per year, and midsized lemon trees that have been growing for five years need 1 pound of nitrogen, or 4 3/4 pound of ammonium sulfate.

Aluminum sulfate or alum is sometimes used by gardeners to lower pH. The pH reduction occurs relatively quickly.
