lannoitusta

Lannoitusta refers to the practice of adding nutrients to soil or crops to maintain fertility and support growth. It covers both mineral fertilizers and organic amendments and aims to supply the essential nutrients that crops require in sufficient and balanced amounts. The goal is to sustain soil health, optimize yields, and improve crop quality while considering environmental and economic factors. In many contexts, lannoitus is integrated with soil testing, crop planning, and sustainable nutrient management.

Nutrients supplied include macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), as well as secondary nutrients like calcium (Ca), magnesium (Mg), and sulfur (S), and micronutrients such as iron, manganese, zinc, and others. Fertilizers may be inorganic blends or organic materials such as manure, compost, composted plant material, bone meal, or green manures. Some practices use slow-release or controlled-release formulations and foliar applications to meet critical needs.

Application methods vary. Fertilizers can be broadcast across the field, banded near seeds or roots, incorporated into the soil before sowing, or delivered through irrigation (fertigation). Timing often includes a base dressing before planting and additional top-dressings during growth, adjusted to crop needs, growth stage, and soil conditions. Soil tests and plant tissue analysis help determine rates and avoid over- or under-fertilization.

Environmental considerations are central to lannoitus. Overuse or improper placement can cause leaching, runoff, eutrophication, and soil salinization. Therefore, nutrient management plans, precise application, proper storage and handling, and adherence to labeling and regulations are encouraged to minimize environmental impact while maintaining productivity.
