Fertilizing young trees – A quick guide

The importance of nutrition In the first years after planting, the seedlings have not fully developed a root system and have increased nutrient needs. The limited absorption capacity of the soil makes it critical to have a proper external supply of essential elements. A balanced fertilization enhances: The creation of a strong root structure, The […]

What is leaf diagnostics?

What is it and how does it differ from soil analysis? Foliar diagnostics is a laboratory method for determining the concentration of nutrients within plant tissues, mainly leaves. Unlike soil analysis which provides information on the availability of elements in the soil, foliar diagnostics shows us which elements were ultimately absorbed by the plant, i.e. […]

When do we use water-soluble fertilizers?

Definition and methods of application Water-soluble fertilizers are formulations that dissolve completely in water and are applied either through the irrigation system (water fertilization) or by foliar sprays. Due to their form, they provide rapid and immediate availability of nutrients to the plant, making them ideal for periods of increased demands or for corrective interventions […]

Fertilization in alfalfa

Introduction Alfalfa, as a perennial legume crop of high nutritional value for fodder, has the capacity for biological nitrogen fixation through symbiosis with root bacteria. However, its nutritional adequacy largely depends on the rational supply of macronutrients, mainly phosphorus (P), potassium (K) and sulphur (S), which determine the yield and longevity of the plantation. Nitrogen: […]

The importance of basic fertilisation

The first application that determines the course of the crop Basic fertilisation involves the initial application of nutrients to the soil, either before or at planting/seeding. It is the fundamental nutritional intervention on which the productive potential of the crop is built. Especially in crops such as cotton, wheat, maize, corn, olive and rice, the […]

Why you need to know the soil pH

When fertilisation doesn’t work, is it the pH? Often, despite the correct application of fertilisers, crops show signs of slowing down, such as delayed growth, yellowing of leaves or reduced production. In such cases, the problem is not necessarily due to a lack of nutrients, but to the reduced ability of the plant to absorb […]

Citrus fruits and iron

Chlorosis on young citrus leaves: the main cause is iron deficiency In many citrus growing areas, intense yellowing is occasionally observed on young leaves, with characteristic retention of the green colour along the ribs. This phenomenon, known as midvein chlorosis, is an indicative symptom of iron (Fe) deficiency, which mainly affects new growth due to […]

Potassium in the potato

Visually healthy crop, but low production? Check potassium levelsThere are many cases where the potato looks healthy above ground, but at the end of the growing season it yields small, amorphous or soft tubers. Thecause, in most cases, is not pathogens, but a deficiency in potassium –a vital element for potato cultivation. Potassium is involved […]

Olives and fertilisation with boron

The olive tree, one of the most emblematic trees of the Mediterranean, has special nutritional requirements. Among the various nutrients, boron (B) emerges as a very essential trace element with a crucial role in its cultivation. Physiological role of boron in the olive tree Effect on flowering and fruiting Boron in all the reproductive processes […]

Fertilisation in rice

Nutrients and their importance in rice cultivation Nitrogen Nitrogen is arguably the most important nutrient for rice cultivation, directly affecting plant growth, leaching and ultimately production. However, flooding conditions pose significant challenges in its management: Phosphorus Phosphorus also plays an important role in the early stages of rice growth, affecting the development of the root […]
