Summer Nutrition Playbook

8 January, 2026

 

Summer presents significant challenges for turf managers, primarily due to stress associated with high light intensity, elevated temperatures, and variable soil moisture. These conditions not only reduce photosynthetic efficiency but also accelerate sugar depletion, leaving turf vulnerable to decline.

Plants rely on carbohydrates (sugars) produced through photosynthesis to build roots, shoots, and stems, and to store energy for stressful periods. When sugar production slows under heat stress and respiration accelerates, reserves drop sharply. This imbalance is the critical challenge of summer. Effective nutrition planning during this period is essential to maintain turf energy and performance.

The aim of summer nutrition is to support availability of sugars and amino acids to sustain energy and aid moisture availability in rhizosphere.

Characteristics of Summer

√ High light intensity and temperatures.

√ Cool season turf growth can decline.

√ Variable soil moisture quality and quantity.

√ CSG depletes energy reserves as photosynthesis is compromised by high temps and light intensity. Reduced sugars make synthesis of amino acids challenging. Amino acids are the turf’s building blocks.

Key management areas during summer

√ Turf stress

√ Turf energy

√ Water quality

√ Soil moisture and health

Managing turf stress

GOING INTO STRESS

√ Manage growth rate to growth potential – use of PGRs to control excess growth.

MP Reinforce throughout Summer to harden leaf.

√ Apply MP Vitalise to supply amino acids throughout Summer.

MP Filter Plus to supply stress hormones to trigger turf stress mechanisms

IN STRESS

√ Minimise nitrogen but keep supplying small amounts.

MP Foundation and MP Energise for immediate energy supply.

MP Vitalise at 20-40 L/ha if turf decline

TriActiv 12-24 L / Ha as a curative solution for turf under stress

MP Safe K if poor quality water.

COMNG OUT OF STRESS

√ Rebuilding energy reserves and stimulate new growth:

MP Vitalise
MP Refresh – start new growth.
MP Safe N – stimulate extra turf growth.
TriActiv 10L / Ha

Recovery Plan

√ Re engineer rhizosphere.

√ Provide carbon as food for soil biology.

√ Build carbohydrates back up.

√ Prepare warm season grass for winter dormancy.

Moisture Management

Maintain moisture in the rhizosphere to keep soil biology connected.
