The relative merits of different phosphorus fertilizers for crops can be easily misunderstood. Most confusion surrounds monoammonium phosphate (MAP) and diammonium phosphate (DAP), especially when technical information is used to promote one of these fertilizers over the other.
At Back Paddock Company we endeavor to keep our customers up to date with the latest tools and information to be able to better service the end-users of our technology. Periodically this means adding in new analyses and calculations that help improve productivity, profitability, sustainability, and minimize risk and the offsite impacts of added nutrients.
Soil acidity is a natural consequence of highly productive food production systems. Soil acidification was recognised, written about and treated with liming materials in Roman times. The need for liming is not necessarily pointer to poor farming practice, more likely these days an indicator of a high soil productivity.
Quite frequently as a result soil analysis comments are made that soils are sodic, magnesic saline, or all of the above. In many cases these terms are not clearly understood and implication for soil management and their effect on crop performance sometimes confused.
SoilMate® user queries on appropriate lime and gypsum products, amendment mixes and specific rates prompted Back Paddock to develop a soil amendment module that makes it easier to make decisions about the most appropriate soil amendment and its application rate
