Potassium amendments

All chemicals were used as received. PDADMAC and PAMPS were obtained from Aldrich Chemical Co. (Milwaukee, WI). Diclofenac sodium, sodium sulfathiazole, labetalol HCl, propranolol HCl, verapamil HCl, and diltiazem HCl were purchased from Sigma Chemical (St. Louis, MO). Dextrose USP was obtained from Amend Co. (Irvinton, NJ). Water was distilled and deionized using a Nanopure purihcation system (Fischer Scientihc, Fair Lawn, NJ). Simulated intestinal fluid was prepared using a O.OIM phosphate buffer (sodium phosphate monobasic and potassium phosphate dibasic) at pH 7 and 5.5 with different amounts of NaCl to vary the ionic strength. Simulated gastric fluid (pH 1.5) was prepared with concentrated HCl with different amounts of NaCl to vary the ionic strength.

Rehnements of the Taylor and McLennan (1985) model are provided by McLennan and Taylor (1996) and McLennan (2001b). The latter is a modihcation of several trace-element abundances in the upper crust and as such, should not affect their compositional model for the bulk crust, which does not rely on their upper crustal composition. Nevertheless, McLennan (2001b) does provide modihed bulk-crust estimates for niobium, rubidium, caesium, and tantalum (and these are dealt with in the footnotes of Table 9). McLennan and Taylor (1996) revisited the heat-flow constraints on the proportions of mahc and felsic rocks in the Archean crust and revised the proportion of Archean-aged crust to propose a more evolved bulk crust composition. This revised composition is derived from a mixture of 60% Archean cmst (which is a 50 50 mixture of mahc and felsic end-member lithologies), and 40% average-andesite cmst of Taylor (1977). McLennan and Taylor (1996) focused on potassium, thorium, and uranium, and did not provide amended values for other elements, although other incompatible elements will be higher (e.g., rubidium, barium, LREEs) and compatible elements lower in a cmst composition so revised. 

Cause Potassium deficiency. Prevent problems by spraying plants with seaweed extract every 2 weeks. Check soil potassium with a soil test and amend as necessary. 

In addition to problems outlined in the cabbage entry, a combination of cold injury and viral disease can cause leaves with black specks. Destroy infected plants. Caterpillars will bore small holes into sprouts see Leaves with large, ragged holes on page 56 for more details and controls. Plants deficient in potassium have poorly developed sprouts Spray with seaweed extract at transplanting and repeat several times to prevent problems. Check potassium levels with a soil test, and amend as necessary. 

Roots poorly formed or pale. Causes Nutrient deficiency extreme temperatures. Spindly, short roots can be caused by potassium deficiency or excessive heat. Poor color and taste are caused by magnesium deficiency, phosphorus deficiency, and low or high temperatures. Copper deficiency can also cause poor root development. Spray foliage with seaweed extract to prevent deficiencies. Do a soil test and amend soil as needed. 

Celery is a heavy feeder. Boron deficiency causes brown, mottled leaves and horizontal cracks on stalks. Florida 683 is tolerant of low boron. Calcium deficiency causes the center of the plant to blacken and die. Utah 52-70R Improved is tolerant of low calcium. Magnesium deficiency causes yellow leaves. Discolored streaks on stalks are a symptom of potassium deficiency. Phosphorus deficiency causes plants to form rosettes. Prevent problems by adding plenty of compost to the soil and by spraying plants with seaweed extract every 2 weeks. Check suspected deficiencies with soil tests and amend soil as needed. 

Ears with bare, undeveloped tips can also be caused by potassium deficiency. Phosphorus deficiency also causes small, irregular ears. See page 77 for an illustration of this condition. If ears are misshapen and kernels have corky, brown bands at their bases, suspect boron deficiency. Spray young plants with seaweed extract or compost tea to help prevent deficiencies. Confirm deficiencies with a soil test and amend soil as needed. 

Bulbs with thick necks that do not cure well. Causes Potassium deficiency seed stalk formation. Confirm deficiency with soil test and amend soil as needed before planting. Use bulbs with thick necks first. 

Peppers require deeply worked, well-drained soil with lots of organic matter. They do best at a pH between 6.0 and 6.8, but tolerate pH as low as 5.5. Peppers require a moderate to high level of nitrogen and moderate levels of phosphorus, potassium, and calcium. Have the soil tested and amend as needed before planting. Peppers grow best between 65° and 80°E Temperatures above 85° or below 60°F can cause blossoms to drop without setting fruit. 

Phosphorus or potassium deficiency can cause spots or patches of dark flesh. Oversize tubers with hollow centers may also indicate potassium deficiency. If deficiencies are suspected, have soil tested and amend as needed. If plants show symptoms of phosphorus deficiency, raise soil pH to 6.0 so the mineral will be more available to the plants. 

Spinach requires moderate levels of potassium and phosphorus and high levels of nitrogen. It is also sensitive to low levels of calcium and boron. Have the soil tested and amend as necessary. Fast-acting sources of nitrogen, such as bloodmeal and soybean meal, are good fertilizers for spinach. 

Sweet potatoes prefer loose, well-drained soil with a pH between 6.0 and 6.5. They require moderate amounts of nitrogen and boron, moderate to high levels of phosphorus, and high levels of potassium. Have the soil tested and amend as necessary before planting. Sweet potatoes do well in raised beds. Work in lots of organic matter before planting. Avoid top-dressing after early summer, or root formation may be interrupted. 

Potatoes long and spindly. Causes Potassium deficiency growing season too short. Check for deficiency with a soil test and amend soil as necessary. Sweet potatoes need a long growing season. Prevent problems by planting cultivars suited to your region. 

Potassium fluoride was the only F salt considered in this report The WATEQ model uses Equation 2 for the individual-ion activity coefficient of F , which causes deviations from the experimental data at concentrations greater than 0.1 molal. The amended WATEQ and fit models used the parameters calculated from the parameters of Pitzer (19) for KF solutions, and both models reproduce the experimental data... 

Setting the national standard for iodine content in table salt at 28-55 ppm potassium iodate (KIO3) (16.6-32.6 ppm iodine) (by a subsequent amendment, dated 1 July 1996). 

TTie specification M1L-P-223B (1962 with Amendment 1—1963) is mandatory for all Department of Defense uses. Its formula is given under No. 146. Black powder is not strictly a mechanical mixture of potassium nitrate, sulfur, and charcoal. During the ball-milling phase of mixing the charcoal and sulfur, the latter is forced into the porous structure of the carbon. This makes the individual grain very dense. Hard compressed larger pellets or columns are relatively nonporous, so that they burn in orderly fashion. 

Surface amendment of thiosulfate products was also tested for reducing 1,3-D emission after soil treatment using packed soil columns or field plots (27). In packed soil columns, it was found t the reduction in 1,3-D emission was proportional to the amount of ammonium thiosulfate used when the amount of water (as carrier for ammonium thiosulfate) was fixed, and to the amount of water sprayed when the amount of ammoniiun thiosulfate was fixed (Table 5). When ammonium thiosulfate wi used at 64 g m the emission of 1,3-D decreased from 33% to 12% when the amount of water was increased firem 1 mm to 9 mm (Table 5). When the water application rate was kept at 9 mm, 1,3-D emission loss decreased from 15% to only 3% when die rate of ammonium thiosulfate was increased from 64 g m to 193 g m. Under similar conditions, the total emission loss of 1,3-D from untreated columns was 43-47%. In field plots, the emission loss of 1,3-D was observed to decrease from 25% in unamended plots to about 5% in ammonium thiosulfate-amended plots. In addition, application of either ammonium or potassium thiosulfate to field plots did not significantly inhibit the effectiveness for nematode control. 

The use of nitrates and nitrites in cured meat products must comply with the provisions set out in Directive 2006/52/EC, which amends Directive 95/2/EC on additives other than colours and sweeteners. Currently authorised as food additives are sodium and potassium nitrites and sodium and potassium nitrates that may be sold only in a mixture with salt or a salt substitute. The indicative ingoing amount of potassium and sodium nitrites that are authorised for use are 150mg/kg and the residual amount is 50mg/kg (KNOj) in non-heat-treated, dried meat products, 100 mg/kg (NaNOj) in other cured meat products, canned meat products and 175 mg/kg (NaNOj) in cured bacon. The indicative ingoing amount of potassium and sodium nitrates is 300 mg/kg in all cured products and the residual amount in cured and canned meat products is 250 mg/kg, in pickled herring and sprat 200 mg/kg and in hard, semi-hard and semi-soft cheeses and dairy-based cheese analogues 50 mg/kg. 

Soil pH is a measure of the soil acidity or soil alkahnity. Because pH can affect the availability of nutrients, it is an important consideration for soil quality. Most crops prefer a neutral or slightly acidic soil. The pH is controlled by the addition of amendments to the soil the addition of minerals such as hme (calcium hydroxide Ca(OH)j) can increase the soil pH, whereas nitrogen-containing amendments lead to increased acidification. Fertilizer can also be added to the soil to ensure the availability of nutrients, specifically the macronutiients nitrogen, phosphorus, and potassium.
