Nitracal-100 TM

Liquid Calcium Ion Exchange Compound with Soil Conditioner

Technical Data

Product Description

Nitrcal-100 is a highly water soluble, liquid calcium and nitrogen concentrate for on-site remediation of oil field related salt water contamination of agricultural land, salt water disposal pit sludge, and salt contaminated drill cuttings and bio-cells. Due to the physical density of Nitracal-100, it must be diluted with fresh water and Nitracal-SC soil conditioners prior to site specific applications.

As soils are saturated with oil field produced salt water, sodium (Na+) readily displaces cations and secondary nutrients naturally occurring in soils, like calcium (Ca 2 +), magnesium (Mg 2 +) and potassium (K+), by "mass ion effect." The exchange of these cations absorbed on the surface of clay mineral colloids for copious amounts of sodium ions faciliates the leaching of beneficial cations from the soil profile. The mobility of clay particles or the natural spacing of clay particles to one another (pore space) is retarded, resulting in soil compaction. Intense adhesive forces between capillary water in discontinuous pore spaces to clay particles (hydrogen-bonding) not only traps soil water but inhibits movement of excess water. The resulting chemical imbalance or lack of CO 2 and O 2 in the soil water is not conducive to plant growth and natural biological activities.

Sodium in soils and pit sludge can readily be displaced by the concentrations of calcium ions in Nitracal-100 when used with Nitacal-SC and fresh water flushes. The slightly anionic nature of Nitracal-SC reverses the partially covalent hydrogen-bonding effects of capillary water to clay particle and allows clay particles to move closer together. The reduction of space between particles in one micro-region results in increased distances between particles of another micro-region of the soil mass, creating pore space and soil drainage. Physical and nutrient fertility returns to the soil profile as Nitracal-100, Nitracal-SC and excess water move through barrier layers.

Anions can also contribute to the toxicity of salt water spills. Boron is a micronutrient, essential for plant cell wall, seed, and pollen formation, but toxic to plants at 1 ppm. However, the calcium in Nitracal-100 will combine with boron to form calcium borate, which is readily taken in by plants.

Effects of Salinity on Crops

Agricultural crops and grasses can have moderate to high tolerances for saline to sodic conditions (measured as percent decrease in crop production). An assessment of salt in soils and its effect on crops and grasses are outlined in the following (scale is based on electrical conductivity values in milliohms per centimeter at 25 o C).

Other parameters commonly considered for remediation of salt damaged soils include: SAR (sodium absorption ratio), CEC (cation exchange capacity), ESP(exchangeable sodium percentage), pH, and SSP (soluble sodium percentage).

Application

Sandy soils usually require less Nitracal-100 for the removal of sodium from the top 18 to 24 inches of surface soil than heavy clay soils, but there are always exceptions. The general guidelines or application rates listed below for Nitracal-100, fresh water, and Nitracal-SC apply to sites having a clay loam soil profile (zero slope) with permeability problems. In order to expedite recovery, it is highly advised that additional fresh water flushes by vacuum truck or irrigation be applied several times after initial treatment. A trained professional should always be consulted for determining site specific conditions with analytical data and site preparations (leveling, tilling and composting). It is always recommended that the installation of a tile drainage system be considered for safe containment of potential environmental pollutants.

Note: Iron oxide and iron sulfide in oil field produced waters will cause high or inconsistent EC readings.
