Сухий ґрунт потребує поливу.

Because the verb потребувати / потребуватися normally takes the genitive case in Ukrainian.

So:

• потребувати що? is not the pattern here
• instead, it is потребувати чого? = to need something with genitive

That is why:

• dictionary form: полив = watering / irrigation
• in the sentence: поливу = genitive singular

So Сухий ґрунт потребує поливу is structurally like:

• The dry soil needs watering
• literally: Dry soil needs of-watering

This is a very common thing learners need to remember: some Ukrainian verbs require a different case than an English speaker might expect.

Сухий ґрунт is in the nominative singular.

Why?

• ґрунт is the subject of the sentence
• the subject is normally in the nominative
• сухий agrees with ґрунт in gender, number, and case

So here we have:

• ґрунт — masculine singular nominative
• сухий — masculine singular nominative to match it

This agreement is a basic feature of Ukrainian adjectives.

Потребує is the 3rd person singular present tense form of потребувати.

That matches the subject:

• ґрунт = soil → singular
• so the verb must also be singular: потребує

A quick pattern:

• я потребую — I need
• ти потребуєш — you need
• він / вона / воно потребує — he / she / it needs
• вони потребують — they need

Since soil is treated as it, потребує is the correct form.

Both can relate to earth / ground / soil, but they are not always interchangeable.

• ґрунт usually means soil, especially in a physical, agricultural, or scientific sense
• земля can mean earth, land, ground, or soil, depending on context

In this sentence, ґрунт is a very natural choice because we are talking about soil that needs watering.

Compare:

• сухий ґрунт — dry soil
• земля суха — the ground/earth is dry

So ґрунт sounds a bit more specifically like the soil itself.

The letter ґ is pronounced like a hard g in English go.

So:

• ґрунт begins with a real g sound

This is important because Ukrainian also has г, which is usually pronounced differently, more like a voiced h sound.

So:

• ґ = hard g
• г = a softer, throatier sound, often compared to h

For many learners, ґрунт is a useful word for hearing that contrast.

It can mean either, depending on context.

The noun полив refers to the act or process of applying water. In English, that might be translated as:

• watering
• irrigation

In a simple everyday sentence like this, watering is often the most natural translation. In agricultural or technical contexts, irrigation may fit better.

So потребує поливу can mean:

• needs watering
• needs irrigation

Both are possible, depending on the situation.

The word order here is neutral and very natural:

• Сухий ґрунт потребує поливу.

It follows a common pattern:

• subject + verb + object/complement

But Ukrainian word order is more flexible than English word order. You can change it for emphasis.

For example:

• Поливу потребує сухий ґрунт.
  This puts extra focus on поливу or on the fact that it is the dry soil that needs it.

The original version is the most straightforward one for learners.

Because Ukrainian has no articles.

English uses:

• a dry soil / the dry soil

Ukrainian simply says:

• сухий ґрунт

Whether it means a dry soil, the dry soil, or dry soil depends on context.

In many cases, English translations will choose:

• The dry soil needs watering or
• Dry soil needs watering

Ukrainian leaves that distinction unstated unless context makes it clear.

Yes, you can, and it would be understandable and natural in many contexts.

You would need to change the adjective because земля is feminine:

• суха земля — dry ground / dry soil

So:

• Суха земля потребує поливу.

That said, ґрунт is often the better choice when talking specifically about soil in a practical or agricultural sense.

So the difference is mostly about nuance:

• ґрунт — more specifically soil
• земля — broader, can be ground / earth / land / soil

Yes, it is completely natural to use сухий for soil.

Сухий means dry and can describe many things:

• сухий хліб — dry bread
• сухе повітря — dry air
• суха шкіра — dry skin
• сухий ґрунт — dry soil

The adjective changes its ending to match the noun:

• masculine: сухий
• feminine: суха
• neuter: сухе
• plural: сухі

So сухий ґрунт is exactly what you would expect grammatically and semantically.

It can do both, depending on context.

Сухий ґрунт потребує поливу can mean:

• a general statement: dry soil needs watering
• a specific present situation: this dry soil needs watering

Ukrainian present tense often covers both ideas, just like English sometimes does.

So without extra context, the sentence is slightly flexible. That is normal.

The dictionary forms are:

• сухий — dry
• ґрунт — soil
• потребувати — to need
• полив — watering, irrigation

In the sentence:

• сухий stays in its basic masculine nominative singular form
• ґрунт stays in its basic nominative singular form
• потребує is the conjugated verb form
• поливу is the genitive singular form of полив

This is a good sentence for seeing how only some words change while others stay in dictionary form.

A useful breakdown is:

• Сухий — adjective, masculine singular nominative
• ґрунт — noun, masculine singular nominative, subject
• потребує — verb, 3rd person singular present
• поливу — noun, masculine singular genitive, governed by потребує

So the sentence structure is:

• [subject] + [verb] + [genitive noun after потребувати]

That makes this sentence especially useful for learning two important things at once:

1. adjective-noun agreement
2. verbs that require the genitive case
