Plastics for Vegetables in Guanajuato: Bajío Guide

What Bajío conditions define the plastic you need?

The Bajío of Guanajuato produces vegetables nearly year-round: broccoli, lettuce, onion, garlic, asparagus, carrot, chile, tomato and strawberry, among others. That variety coexists with a climate of cool winter nights, occasional frost in the higher areas and strong heat toward spring. In addition, much of the irrigation depends on groundwater, a resource that costs more to protect each cycle.

That is why plastic is not chosen by fashion, but by three questions: what temperature the root needs, how much water can be lost to evaporation and how much weed and pest control is required. From there come the three ICUSA solutions that make the most sense in the region: agricultural mulch film in open fields, greenhouse ground cover in protected agriculture and hydroponic grow bags in soilless crops.

When does agricultural mulch film make sense for Guanajuato vegetables?

Mulch film covers the planting bed and modifies the microclimate around the plant. Our technical data sheet says it makes water and nutrient use more efficient, controls weeds and pests and modifies soil temperature. It makes the most sense in long-cycle or high-value vegetables, where drip tape irrigation is already installed and you want to make the most of every liter.

Which mulch film color goes with each season?

Color decides whether the soil warms up or cools down. This guide summarizes what the technical data sheet says and how it typically fits in the Bajío:

If your farm has fields with different exposure or altitude, it is not unusual for one color to suit the cold field and another the warm one. A technical advisor can help you decide based on your planting calendar.

Which perforation and gauge should you choose?

Our technical data sheet mentions center, staggered (tres bolillos), domino, three-row and multi-perforated patterns, plus custom pre-perforations. The spacing between plants of your crop sets the perforation. Mulch film comes in gauges from 70 to 200, and the gauge depends on how long the film must last and whether it will be lifted with machinery at the end of the cycle. A maximum lifespan of up to 2 years is stated, depending on crop, gauge and use. For single-cycle crops, there is no need to pay for durability you will not use.

What mistakes should you avoid when laying mulch film?

Almost all field problems come from the laying, not from the film. Laying over a well-formed, firm bed with the right moisture helps the plastic fit tightly and stay down in the wind. A film that is too tight tears at the perforation, and one that is too loose moves with the gusts. If you use drip tape, place it before covering. At the end of the cycle, removing all the plastic prevents leftovers from staying in the field for the next crop.

What is greenhouse ground cover for in the Bajío?

In tomato, bell pepper or cucumber greenhouses, the space between rows is usually exposed soil: it raises dust, lets weeds grow and makes cleaning harder. Greenhouse ground cover is a plastic covering for those aisles, protects the crop from dust, prevents weed growth, makes phytosanitary control easier when pruning, defoliating or harvesting, and reflects solar radiation toward the foliage, which supports photosynthesis.

In a region with a lot of wind and dust storms in spring, dust on the leaf is a real problem, and the ground cover makes daily work cleaner and more hygienic. It combines well with a greenhouse cover with anti-dust treatment.

When does the hydroponic grow bag make sense?

The hydroponic grow bag is the container where the plant grows without soil, in a pot or pillow format. The technical data sheet describes it as an option that is easy to handle and store, lower in cost than other containers, that makes disinfection easier when reusing the substrate and gives more control over pests, diseases, water and nutrients.

There are two colors. The white/black bag reflects sunlight and helps lower temperature. The black/black absorbs more heat and raises the temperature around it. In the Bajío, the white/black makes sense for hot cycles, and the black/black for cold months or unheated greenhouses.

Which plastic goes with which crop and season?

What should you check before asking for a quote?

So the advisor can recommend well, have these details at hand: crop and spacing between plants, planting date, bed width, whether you use machinery to lay and lift the film, and whether the farm is open field or greenhouse. It is also worth reviewing the usage recommendations and the warranty and replacement policy before deciding.

If you want to compare with other regions, the guide to agricultural plastics by state covers the essentials. And if your Guanajuato production includes protected agriculture, you will find it useful to read about greenhouses and macro tunnels in Jalisco and about the use of blue and yellow chromatic traps.
