Nutrient Use Efficiency: Why is it Important to Crop Yields?

At IntraCrop, we are dedicated to helping growers maximise nutrient use efficiency (NUE), ensuring that essential nutrients such as nitrogen, phosphorus, and carbon are utilised more effectively by crops. By improving NUE, we can enhance crop health, increase yields, and support more sustainable farming practices.

Nutrient Use Efficiency (NUE) refers to the plant’s ability to optimise the uptake and utilisation of nutrients, leading to improved growth, yield, and environmental sustainability. Efficient nutrient use reduces losses to the environment, maximising fertiliser investments and contributing to sustainable food production.

Why do plants need phosphorus?

Plants need phosphorus because it is essential for several critical biological processes, including: energy transfer, root development, photosynthesis, seed and fruit formation, cell membrane integrity and stress resistance. Due to its limited availability in many soils, improving Phosphorus Use Efficiency (PUE) is vital for sustainable agriculture. Biostimulants like Status® can enhance phosphorus uptake, ensuring better nutrient use and crop performance.

Why do plants need nitrogen?

Nitrogen is a fundamental nutrient that supports growth, development, and overall plant health. It supports protein and enzyme formation, chlorophyll production, leaf and vegetative growth, ATP formation, improved crop yield and stress resistance. Because soil nitrogen is often depleted quickly, enhancing NUE is crucial for maximising crop productivity while reducing environmental impact. Biostimulants like Status® can help plants utilise nitrogen more effectively, leading to better yields and sustainability.

Why do plants need sulphur?

Plants need sulphur for several essential functions, including: protein and enzyme formation; chlorophyll production; vitamin and oil production(essential for oil-producing plants like mustard and rapeseed); improved disease resistance; enhancing nitrogen use efficiency; and influencing flavour in crops like onions, garlic, and mustard. Sulphur deficiency in plants can lead to pale or yellow leaves, stunted growth, and reduced crop yields.

Information

Improving Phosphorus Use Efficiency (PUE)

Phosphorus (P) is vital for root development, energy transfer (ATP), and crop maturity. However, phosphorus availability is often limited in soils due to fixation in insoluble forms, making it a critical challenge for growers.

Recent research demonstrates that Status® can significantly improve phosphorus uptake and assimilation, leading to better root growth, higher nutrient content, and increased crop resilience.

  • Root and shoot biomass: Status® has been shown to increase root dry weight by 16.7%, supporting deeper nutrient access.
  • Chlorophyll enhancement: Treated plants showed up to a 30% increase in chlorophyll content, boosting photosynthetic efficiency.
  • Higher nutrient absorption: Status® increased phosphorus uptake by 20%, nitrogen by 17%, and carbon by 10%.

By enhancing PUE, Status® supports higher crop productivity while reducing the need for excess phosphorus fertilisers, helping growers meet sustainability targets.

Increasing Nitrogen Use Efficiency (NUE)

Nitrogen use efficiency is affected by multiple factors, including soil composition, environmental conditions, and crop characteristics. Soil elements such as pH, texture, and organic matter levels influence nitrogen availability and how effectively plants absorb it. Weather conditions, including temperature, precipitation, and sunlight, determine nutrient uptake and utilisation throughout different growth phases. Additionally, crop genetics play a crucial role, as different plant varieties exhibit varying capacities for nutrient absorption and efficiency.

Fertiliser application methods and timing also have a significant impact on nitrogen utilisation. Trials with Status®, Talisman®, and Nutrino Pro have consistently demonstrated improvements in nitrogen use efficiency and associated physiological benefits across various crops.

Results have shown:

  • Up to 40% increase in root growth
  • 15% increase in shoot growth
  • An average yield improvement of nearly 6%
  • Up to 95% enhancement in NUE

All achieved with reduced traditional nitrogen fertiliser inputs. Status® holds a CE-mark specifically for nitrogen use efficiency.

The Role of NUE in Sustainable Agriculture

Enhancing nutrient use efficiency is a key strategy for improving both productivity and sustainability in modern farming:

  • Increases yield by ensuring crops absorb and utilise nutrients effectively.
  • Reduces fertiliser waste and limits environmental runoff, particularly for phosphorus.
  • Supports regulatory compliance with sustainable farming initiatives.
  • Enhances plant resilience to stress factors such as drought and nutrient deficiencies.
Frequently asked questions

What is Nutrient Use Efficiency (NUE)?

Nutrient Use Efficiency refers to the ability of plants to optimise the uptake and use of nutrients like nitrogen, phosphorus, and carbon. High NUE means crops can produce more yield with less fertiliser, reducing waste and environmental impact.

Why is improving NUE important for growers?

Increasing NUE helps maximise fertiliser investment, boost yields and reduce nutrient losses to the environment. This supports both profitability and sustainable farming goals.

How can biostimulants improve NUE?

Biostimulants such as Status®, Talisman® and Nutrino Pro can increase root biomass, improve nutrient uptake and enhance nitrogen and phosphorus assimilation, resulting in better crop performance under both healthy and stressed conditions.

What role does nitrogen play in plant growth?

Nitrogen is essential for chlorophyll production, protein synthesis, enzyme activity and vegetative growth. Without enough nitrogen, crops suffer reduced yield and poor resilience to stress.

What role does phosphorus play in plant growth?

Phosphorus supports energy transfer (ATP), root development, seed and fruit formation and overall plant resilience. Because it is often locked up in soils, improving Phosphorus Use Efficiency (PUE) is critical for sustainable agriculture.

Why is sulphur important for crops?

Sulphur is needed for protein and vitamin production, chlorophyll formation, oil content in crops like rapeseed, disease resistance, and even flavour in certain vegetables. Deficiency can lead to yellow leaves, stunted growth, and yield loss.

How much can NUE be improved with biostimulants?

Trials with Status®, Talisman®, and Nutrino Pro have shown up to a 40% increase in root growth, 15% increase in shoot growth, nearly 6% average yield improvement, and up to 95% enhancement in NUE compared with traditional fertiliser use.

Does improving NUE reduce fertiliser costs?

Yes. By making better use of existing nutrients, growers can often reduce fertiliser inputs without compromising yield, saving costs while meeting environmental and regulatory requirements.

How does NUE support sustainable agriculture?

Increased NUE reduces nutrient runoff into waterways, limits greenhouse gas emissions from fertiliser use and helps farmers comply with sustainability and climate-focused regulations, all while maintaining or improving crop yields.
