The environmental impact of Nitrogen fixing trees

The usage of Nitrogen fixing trees will change the environment. The addition of moist, shade, mulch and nitrogen will create zones of different properties.
“We found a higher number of shrubs under canopies, whereas that of grasses and perennial forbs increased in intercanopy areas. Concentrations of organic matter, nitrogen, potassium and phosphorus, factors limiting biological productivity in Monte desert soils, were significantly higher under than outside P. flexuosa canopies. Electrical conductivity and concentrations of Na+, Ca++, Mg++ were higher in the northern than in the southern microhabitats. …… We conclude that P. flexuosa modifies the spatial pattern of plant species in the shrub and herbaceous layers and the chemical conditions of the soil, generating spatial heterogeneity on different scales.” (Journal of Vegetation Science Article: pp. 543–550 Effects of Prosopis flexuosa on soil properties and the spatial pattern of understorey species in arid Argentina RossiBertilde E.A, VillagraPablo E
If we translate the scientific gibberish to ordinary English the article simply states that Nitrogen fixing trees create a biological diversity that was not there before. They also enrich the soil in areas of scarcity.
