In Australia, macronutrient fertilizers are labeled with an "N-P-K-S" system, which uses elemental mass fractions rather than the standard N-P-K values and includes the amount of sulfur (S) contained in the fertilizer. [5] Fertilizers with additional macronutrients (S, Ca, Mg) may add more numbers to the N-P-K ratio to indicate the amount. The ...
An auto clicker is a type of software or macro that can be used to automate the clicking of a mouse on a computer screen element. [1] Some clickers can be triggered to repeat recorded input. Auto clickers can be as simple as a program that simulates mouse clicking.
[1] A controlled-release fertiliser (CRF) is a granulated fertiliser that releases nutrients gradually into the soil (i.e., with a controlled release period). [2] Controlled-release fertilizer is also known as controlled-availability fertilizer, delayed-release fertilizer, metered-release fertilizer, or slow-acting fertilizer.
A fertilizer (American English) or fertiliser (British English) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. [1]
Organic fertilizer nutrient content, solubility, and nutrient release rates are typically much lower than mineral (inorganic) fertilizers. [ 38 ] [ 39 ] A University of North Carolina study found that potential mineralizable nitrogen (PMN) in the soil was 182–285% higher in organic mulched systems than in the synthetics control.
An imbalance of C:N ratio causes a slowdown in the composting process and a drop in temperature. When the C:N ratio is less than 15:1, outgassing of ammonium may occur, creating odor and losing nitrogen. [20] A finished compost has a C:N ratio of around 10:1. [19]
Global production of seaweed fertilizer largely phased out when chemical fertilizers were developed in the 1920s, due to the cheaper production cost. [ 25 ] [ 21 ] [ 26 ] Chemical fertilizers revolutionized the agriculture industry and allowed the human population to grow far beyond the limits of traditional food production methods.
Micronutrients are present in plant tissue in quantities measured in parts per million, ranging from 0.1 [3] to 200 ppm, or less than 0.02% dry weight. [4] Most soil conditions across the world can provide plants adapted to that climate and soil with sufficient nutrition for a complete life cycle, without the addition of nutrients as fertilizer.
