How Old Is The Problem of Soil Salinity?

Mashkan-shapir, Mesopotamia 2300 BC

Mashkan-shapir was a typical Mesopotamian city, located about 20 miles from the Tigris River and connected to the river by a network of canals. Despite a flourishing civilization, Mashkan-shapir was abandoned within only 20 years of its settlement around 2300 BC. What could have caused this rapid demise?

Scientists now believe irrigation techniques played an important role in Mashkan-shapir’s collapse. The same process that allowed farming in this region also eventually made it impossible to farm. Irrigation has a Catch-22: if irrigation water is allowed to sit on the fields and evaporate, it leaves behind mineral salts; if attempts are made to drain off irrigation water and it flows through the soil too quickly, erosion becomes a problem. Scientists believe that Mashkan-shapir’s collapse was caused in part by destruction of the fields by mineral salts. When mineral salts concentrate in the upper levels of the soil, it becomes poisonous for plants.

In the United States, California’s San Joaquin Valley faces irrigation problems that are similar to those faced by Mashkan-shapir. The irrigated soil is becoming increasingly salty, as is the water table. Without irrigation, abundant crop yields would have been impossible in this arid area. With irrigation, the land will very likely become impossible to farm.

Modern methods don’t seem to be helping the San Joaquin Valley avoid this fate. Farmers have tried to cleanse the salts from the soil by flushing it with water and draining it into the sea. They have tried pouring the salty runoff from irrigation down drains dug deep into the ground. So far, these solutions have not worked, and the fields closest to the water table are becoming poisoned by salts. Right now, it looks as if the San Joaquin Valley is headed for the same fate as Mashkan-shapir. *

As you can see saline in the soil is an age old problem in need of a solution.

​Universal Agriculture has a different solution that has been used in the past to remediate salt in the soil. We know that we can restore many acres of unusable land to productivity with Salt Fighter. Please contact us to show you how we can help you to manage your soil salinity.

Salt Fighter

Saline Soil Remediation

Salt Fighter works on salt in two ways. One, it dislodges the salt from the soil, second, it binds the salt. Once bound the salt leaches down into the soil; however, it cannot return because it is bound by theSalt Fighter.

​Salt Fighter is the keystone to sodic soil remediation.  Salt Fighter was developed to remediate agricultural land in the Middle East where land had become unusable due to salt buildup over many years of irrigation. Salt Fighter was researched and developed for over ten years in laboratories in Europe and Asia. It has been used extensively in Middle East and North Africa Counties and is now available in the US for the first time.

Salt Fighter replaces gypsum treatment and is a fraction of the price. Gypsum treatment is expensive and in most cases, has to be professionally applied. Price of gypsum application ranges from 200 to 500 dollars an acre and must be applied 1-5 times a year. Gypsum has one mechanism of action. Ca++ ions replace the salt which is then leached into the ground water by additional irrigation water. This salt can return to the surface over time. Salt Fighter treated soil, as stated above keeps the salt bound and will not return. Only new salt from irrigation water needs to be treated as needed.

Application of Salt Fighter is easy. Instead of 2-8 tons of gypsum per acre you only need to add 4.2 liters per acre of liquid Salt Doctor to your irrigation water. Unlike gypsum, no further water leaching is required simply irrigate the land for the requirement of the crop as normal. This saves money by reducing water leaching.

Please note that 2 treatments of Salt Fighter are suggested as a first treatment to bring the soil to the desired level of sodium. Single treatments 1-4 times a year are required dependent on the salt level in the irrigation water thereafter.

Please call us to see how you can use Salt Fighter to restore your soil to its natural level.
