An intelligent system for protecting plants from heat, sun and dehydration

WOOD Summer Shield— a system of summer climate protection for gardens, nurseries, forest plantings, vineyards, vegetable crops and young ecosystems from overheating, sunburn, dry winds and critical moisture loss.

The system combines:

cooling water mist;

reflective mineral aerosols;

temporary shading;

soil protection;

drip irrigation;

microclimate sensors;

TREE AI;

mobile and stationary spraying platforms.

The main purpose of DREVO Summer Shield is not to completely block plants from the sun, but to reduce extreme heat load to a safe level.

1. Main threats in summer

Plants are damaged not only by high air temperatures.

Key factors:

overheating of leaves;

overheating of the bark;

sunburn of fruits;

dry winds;

low air humidity;

hot soil;

water shortage;

a sharp transition from cool weather to heat;

high solar radiation;

night heat without plant recovery.

The surface temperature of leaves and fruits can be significantly higher than the air temperature.

2. Basic protection modes

Cooling Mist

Cooling with fine water mist.

Reflective Shield

Creation of a thin reflective coating on leaves, fruits and bark.

Smart Shade

Automatic or temporary shading.

Soil Shield

Protecting soil from overheating and evaporation.

Dry Wind Protection

Weakening of dry winds and hot winds.

Recovery Mode

Plant recovery after extreme overheating.

3. DREVO Cooling Mist

Principle of operation

Small droplets of water evaporate into the air and absorb heat.

This allows:

reduce the air temperature;

cool the surface of the leaves;

increase local humidity;

reduce transpiration stress;

reduce the risk of sunburn;

create a temporary milder microclimate.

4. Droplet size

ModeDroplet sizePurpose
Ultra-fine fog5–20 micronsCooling the air without causing excessive moisture
Thin fog20–50 micronsCooling of leaves and plants
Fine spray50–100 micronsProtective moisturizing
Large dropsMore than 100 micronsWatering, but not spray protection

Main operating range:

10–50 microns

Droplets that are too small are easily carried away by the wind. Droplets that are too large settle quickly and waste more water.

5. When to turn on the fog

The system can be started by a combination of several factors:

air temperature above 30–35 °C;

leaf temperature is above the safe threshold;

solar radiation is close to critical;

relative humidity is too low;

the dry hot wind is getting stronger;

the plant shows signs of water stress;

Extreme heat is predicted.

The decision must be made not only based on air temperature, but also on:

leaf temperature;

soil moisture;

water vapor pressure deficit;

solar radiation;

wind speed;

the state of the plant.

6. Water supply mode

It is better to use short pulses rather than continuous spray.

Sample cycle:

20-60 seconds of spraying;

3-10 minutes break;

re-evaluation of temperature and humidity;

adaptation of the regime.

Advantages:

water saving;

reducing the risk of fungal diseases;

reducing fruit wetting;

more precise microclimate control.

7. DREVO Reflective Shield

Reflective mineral protection

A very thin, light layer of natural mineral material is applied to the leaves, fruits and bark.

Main options:

purified kaolin;

finely dispersed calcite;

diatomite;

light clay minerals;

special agricultural reflective suspensions.

8. Basic composition of summer suspension

Basic option

water;

purified kaolin;

natural dispersant;

safe plant or polysaccharide stabilizer;

if necessary, an adhesive approved for agriculture.

Purpose of components

ComponentFunction
WaterCarrier
KaolinReflection of solar radiation
DispersantPreventing particle settling
StabilizerUniformity of suspension
AdhesiveRetaining the coating on the plant

9. Coating thickness

The coating must be:

thin;

uniform;

bright;

breathable;

washable;

not interfering with photosynthesis.

The goal is not to cover the plant with thick paint, but to createmicroscopic reflective screen.

10. Which parts of the plant are protected?

Leaves

Reduction of temperature and sun stress.

Fruit

Protection against burns and overheating.

Trunks of young trees

Protecting bark from sun cracks.

Escapes

It is especially important to protect young and thin branches.

Seedling

Reducing post-landing shock.

11. DREVO Smart Shade

Types of shading

shading nets;

retractable screens;

light awnings;

temporary fabric strips;

reflective panels;

agrovoltaic structures;

mobile robotic screens.

12. Recommended degree of shading

Culture or objectShading
Young trees20–40 %
Nurseries30–50 %
Shade-tolerant crops40–60 %
Grapes and fruit crops15–30 %
First year forest plantings30–50 %
Restorative planting in desert conditionsUp to 50–70% at the first stage

Too much shading can:

reduce photosynthesis;

pull out plants;

impair the maturation of shoots;

increase humidity and the risk of fungal diseases.

13. WOOD Soil Shield

Plant protection is impossible without soil protection.

Key measures:

wood mulch;

bark;

a branch;

straw;

compost;

stone mulch in arid regions;

ground cover plants;

shade from bushes;

biochar;

moisture-retaining organic mats.

14. Mulch thickness

MaterialRecommended thickness
Shtepa5–10 cm
Bark5–8 cm
Straw10–15 cm
Compost3–5 cm
A mixture of wood chips and compost5–10 cm
Stone mulchAccording to the project and climate

Mulch should not be placed close to the tree trunk.

15. Protection from dry winds

Wind Shield

Used:

forest belts;

shrub strips;

temporary grids;

hedges;

multi-tiered plantings;

mobile barriers.

The main goal is to reduce wind speed, but not completely stop air movement.

16. Multi-layered protection

Ideal structure:

high tree layer;

middle tier;

shrubs;

herbs;

ground cover plants;

mulch.

This system creates:

shadow;

20. Nanny plants

For natural shading, fast-growing or hardy plants are used, which create a microclimate for more valuable trees.

Functions:

shadow;

wind protection;

moisture retention;

accumulation of organic matter;

soil improvement.

Later, some of the nurse plants can be removed or transferred to the understory.

21. DREVO Summer Shield for nurseries

The system uses:

air temperature;

leaf temperature;

soil temperature;

relative humidity;

soil moisture;

solar radiation;

wind speed;

wind direction;

weather forecast;

plant health chambers;

Thermal imagers.

23. DREVO AI Climate

Artificial intelligence determines:

when to turn on the fog;

how much water to supply;

when to close shade screens;

which areas overheat faster;

where water stress begins;

which plants require priority protection;

when to shut down the system due to the risk of disease;

when watering is required, not just cooling.

24. Operating modes

26. Mobile systems

WOOD Summer Shield Rover

The mobile platform can transport:

water tank;

pump;

fog cannon;

thermal imager;

weather sensors;

kaolin suspension module;

folding screen;

autonomous power supply.

27. Drones

Drones can be used for:

overheating mapping;

thermal imaging search for stress areas;

local application of reflective coating;

control of young plantings;

searching for damage after heat.

Drone spraying is only feasible for spot treatments. For large-scale cooling, it is generally less effective than ground-based systems.

28. Water consumption

DREVO Summer Shield should be different from regular watering.

Fog is used for:

cooling;

increasing humidity;

reducing the sheet temperature.

Drip irrigation is used for:

replenishment of soil moisture.

These two processes cannot be mixed.

29. When fog is harmful

Fog should be limited:

with high night humidity;

in case of active fungal diseases;

during flowering of some sensitive crops;

in strong winds;

before a long, damp night;

if the water has high mineralization;

if a salt coating forms on the leaves.

30. Water quality

Water should be:

no hazardous salts;

no petroleum products;

pathogen-free;

with controlled stiffness;

free of particles that clog nozzles.

For ultra-fine atomization, filtration is required.

31. Colored aerosol indication

Brightly colored smoke should not be used.

For visual control you can use:

white water mist;

weak light mineral aerosol;

safe cloud illumination;

digital display of coverage area;

lidar distribution control.

It is better to create color with light rather than with chemical dye.

32. What not to do

The following is not allowed:

use pyrotechnic colored smoke;

spray unknown dyes;

create dense smoke near people and roads;

apply an excessive layer of minerals;

turn on fog continuously without control;

use salt water;

cool plants with ice water in hot weather;

shade plants completely for long periods of time;

increase humidity in case of fungal diseases;

consider fog as a replacement for root watering;

spray substances without checking their safety for bees and other pollinators.

33. Expected results

reduction in leaf temperature;

reduction of sunburn;

maintaining fruit quality;

reduction of water loss;

increasing the survival rate of seedlings;

reduction of mortality of young trees;

bark protection;

yield stabilization;

reduction of heat stress;

increasing the resistance of plantings to heat waves.

Adjusting the regime

The main principle

In summer, the plant should not be hidden from the sun, but allowed to overheat and lose its ability to manage its own water.

WOOD Summer Shieldcreates a temporary protective microclimate around plants, combining cooling, light reflection, shading, soil protection and precise moisture management.
