Comment appliquer l’agronomie pour développer de nouveaux engrais ?

A agronomia engloba diversas áreas de conhecimento, as quais são aplicadas e avaliadas através de testes a campo, de forma que se obtenha a máxima produtividade com menos perdas no sistema. Busca-se, portanto, fertilizantes mais eficientes, pela maior absorção pelas plantas, com menor impacto ambiental. Dentre as tecnologias disponíveis no mercado, tem-se os biofertilizantes, produtos de liberação lenta e/ou controlada, formulações combinadas etc., e todos tem como objetivo uma maior sustentabilidade. O foco deve estar no P&D, apoiado pelas empresas fabricantes de fertilizantes, universidades e instituições de pesquisa.

By identify crop needs through soil testing, plant tissue analysis, and yield mapping. This knowledge guides the formulation of fertilizers to address deficiencies and how fertilizers are delivered for optimal efficiency. Factors like nutrient availability, placement, and timing are all considered to minimize waste and environmental impact. Finally, agronomy principles are essential for developing sustainable practices like slow-release fertilizers and biofertilizers.

The plant's response to fertilizer applications can be discerned through physiological and yield observations. These observations facilitate the identification of the optimal dosage for a specific crop, considering the particular soil type and prevailing weather conditions

Une chose que j'ai trouvée utile: La base de l'agronomie repose sur la compréhension des principes fondamentaux de la science des cultures et de la gestion des terres agricoles. Cela inclut l'étude des sols, des plantes, du climat, de l'eau et des techniques de culture. L'agronomie vise à maximiser la production agricole de manière durable, en tenant compte des facteurs environnementaux, économiques et sociaux. Elle englobe également la recherche de solutions pour améliorer la productivité, la qualité des cultures et la résilience aux changements climatiques.

The best way to develop new fertilisers should actually base on the soil analysis and and interpretation. The interpretation will guide the the formulation because ecological zones differs in nutrients elements composition. We should get an average soil samples from ecological zone and probably combining the samples to get a far idea on what kind of nutrients elements to combine in what composition!

Fertilizers, crucial for providing essential nutrients like nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and micronutrients to plants, can be categorized into organic and inorganic types based on their origin and composition. Organic fertilizers, sourced from natural materials like animal manure, compost, or green manure, contrast with inorganic fertilizers synthesized from chemical compounds such as ammonia, urea, nitrate, phosphate, or sulfate. Additionally, fertilizers can be classified into solid and liquid forms, delineated by their physical state and application method

Chemical engineers leverage their expertise in kinetics and catalysis to tailor fertilizer formulations, ensuring nutrients are released in sync with plant growth cycles. By integrating agronomic principles, they can design fertilizers that not only meet the precise nutritional needs of crops but also mitigate environmental risks such as eutrophication caused by runoff. Innovations like nano-fertilizers are on the horizon, promising more efficient nutrient delivery and reduced environmental impact.

En fait, on peut ajouter, on doit Planifier l'essai,Préparer le terrain Appliquer des traitements, Suivi de la croissance des cultures. Analyse des résultats : À la fin de la saison de croissance, récolter les cultures et évaluer les rendements, la qualité des produits récoltés et d'autres indicateurs pertinents. Comparer les performances des différents traitements pour déterminer l'efficacité des engrais testés. Interprétation des résultats : Analyser les données collectées pour tirer des conclusions sur les effets des engrais sur la fertilité du sol et la productivité des cultures. Identifier les pratiques d'engraissement les plus efficaces et recommander des recommandations de gestion pour les agriculteurs.

A avaliação da eficiência dos fertilizantes em campo é crucial, através dela saberemos se o fertilizante testado tem efeito ou não sobre o crescimento e desenvolvimento das plantas.

Agronomy informs fertilizer development by understanding plant nutrient requirements and soil health. By integrating agronomy with chemical process engineering, we can design fertilizers tailored to specific crop needs, optimizing nutrient uptake and minimizing environmental impact. Innovations like slow-release and precision fertilizers are direct outcomes of this interdisciplinary approach, addressing both efficiency and sustainability in modern agriculture.
