Why is Precision Farming Needed?

Precision farming saves 15 to 30% on fertilisers, fuel and chemicals. At the same time, yields grow by 20-30%. The secret is simple: each plot gets exactly the resources it needs, not an averaged rate for the whole field. Americans calculated in 2021: fertiliser efficiency rose by 7% with potential to reach 21%, herbicide use dropped by 9%, and atmospheric emissions fell by 15%.

Old Methods No Longer Work

Over the past 20 years, climate has cost Ukraine's agricultural sector 2 billion dollars in losses. That's 12% of what farming contributes to GDP annually. Droughts alternate with floods, soil washes away, temperatures jump.

Add to this the prices for everything: fertilisers, diesel, machinery, land rental. Mineral fertilisers eat up to 40% of production costs. Simply increasing application rates won't work anymore - that's death for profitability.

Americans faced this problem 30 years ago. They found the solution in precision: giving plants what they need, not pouring everything uniformly.

How Money Actually Gets Saved

Variable rate fertiliser application gives the biggest effect. You do soil analysis and see: phosphorus needed here, nitrogen there, and that plot over there needs nothing at all.

Real example: on a field they found a zone covering 11% of the area where phosphorus fertilisers weren't needed at all. With the standard scheme, they'd have applied 255 kg per hectare - into thin air. On another plot with a requirement of 319 kg per hectare, they'd have applied 254 kg - underdosing by 65 kg. The result saved 1.3 tonnes of fertiliser on one field.

Chemicals are saved up to 30%. Section control sprayers work by shutting off nozzles where treatment isn't needed. Scanners read the field on the go and decide where to apply product and where not to.

Seeds can be saved up to 20%. Precision seeding places grains correctly, without gaps or overcrowding. Germination is better, development more uniform.

Yields Grow Without Extra Investment

When each plot gets what it lacks, plants unlock the cultivar's full potential. Not the whole field needs one fertiliser rate - each square needs its own.

Practice shows crop growth of 20-30%. This comes without increasing costs, simply through smart resource distribution.

Fewer machinery passes over the field mean less diesel consumption and less soil compaction. Auto-piloted tractors drive tight, without overlaps. The actual area gets worked, not a notional one with duplications.

What This Gives the Soil

Less chemistry ends up where it's not needed. That means less pollution of water, air and the soil itself. The process becomes cleaner, even though more productive.

Fossil fuel consumption drops by 6%, and with full implementation can reach 22%. CO2 emissions fall by more than 15%.

Soil doesn't receive excess fertiliser where it's not needed. This protects against salinisation or acidification. Fertility is preserved, not washed out over a few seasons.

What's Included in Precision Farming

GPS and autopilot eliminate track overlaps. Machinery output grows by 25%, time is saved by 12%. You don't work the same spot twice.

Yield sensors on combines show productivity across the whole field during harvest. This data goes into calculating fertiliser rates for the next year.

Field maps and satellite imagery give the complete picture of crop condition. Problem zones are visible before they become noticeable from ground level.

Variable rate spraying uses cameras to spot weeds. Product goes on precisely, not blanket across the entire area. Machinery makes decisions in real time whilst moving.

Who Can Use the Technology

The notion that precision farming is only for massive holdings is long outdated. Worldwide, farms from 50 hectares work with these technologies. In Ukraine, farmers from 1,000 hectares are increasingly moving to new methods.

Even on 100 hectares you can save tens of thousands of hryvnias per season. They start with basic things: agricultural navigator and soil analysis.

It pays back in 6-7 years. Seems long, but considering how everything around is getting dearer, the advantages become obvious quickly. Those who've tried don't go back.

How to Start

Around 30% of Ukrainian enterprises already use precision farming technologies. Usually they start with autopilot or course indicator - to avoid overlaps in fields.

First - look at what's already there: machinery, software, sensors. Then draw up a plan for what to add gradually.

Better to start with row crops: sunflower, maize, beetroot. The effect shows fastest on these.

No need to implement everything at once. Choose what suits your farm. The main thing is to have goals and measure results in percentages or money.

What This Gives in Numbers

Farms applying technologies across their entire land bank save 3 to 7%. This includes savings on seeds, fertilisers, chemicals. Plus machinery output grows.

With full soil analysis, efficiency rises to 35%. With current fertiliser prices, the sum works out serious.

Experts estimate savings of 15 to 30% compared with old methods. That's pure benefit without risks or quality loss.

In Brief

Precision farming isn't needed for ticking a box about technology. It's a way to survive in conditions where everything's getting dearer and climate becoming unpredictable. Saving 15-30% of resources plus yield growth of 20-30% isn't theory, but practice of thousands of farms worldwide. The technology is accessible not just to holdings, but to medium-sized farmers from 100 hectares. The main thing is to start.
